(Chemical Equation Presented) The synthesis of nonsymmetrical polyamines (PAs) has, up to now, been problematic due to lengthy synthetic procedures, lack of regioselectivity, and very poor atom economy. An innovative synthetic protocol for nonsymmetrical PAs using a modified Ugi reaction (N-split Ugi) which simplifies the synthesis of these tricky compounds is described. We believe that this new synthesis may open the door for the generation of new and pharmacologically active PAs.

The effect of the nitrogen nonbonding electron pair on the 1JC,H values of 1,3-diazaheterocycles was analyzed and compared to 1,5-diazabiciclo[3.2.1]octanes, which have a restricted conformation. The 1JC,H values were measured by observing the 13C satellites in the 1H NMR spectra and then determining the 1H-coupled 13C NMR spectra. The 1JC,H values are 10 Hz larger when the alpha-hydrogen is synperiplanar rather than antiperiplanar to the nonbonding electron pair on the nitrogen, which serves as experimental evidence of the orbital n N?sigmaC,Hap interactions. In addition, the homoanomeric effect from the interactions of the nitrogen lone pair with the antibonding orbital of the equatorial hydrogen, which was in the beta position, was discussed (nN?sigmaC(beta),H eq).

Dynamic mixtures generated by reversible aminal formation efficiently prolong the duration of evaporation of bioactive volatile aldehydes. Secondary diamines used for the generation of dynamic mixtures are obtained by treatment of primary diamines with carbonyl compounds and reduction of the diimines with NaBH4. The reversibilities of the reactions were demonstrated by NMR measurements in buffered aqueous solutions. Kinetic rate constants and equilibrium constants for the formation and hydrolysis of aminals were determined. The performance of dynamic mixtures as delivery systems for perfumery ingredients was tested after deposition onto cotton, and the long-lastingness of fragrance evaporation was investigated by dynamic headspace analysis against a reference sample. The simplicity of the concept together with its excellent performance makes this delivery system highly interesting for applied perfumery. Reversible aminal formation might also be successfully applicable to dynamic combinatorial/covalent chemistry for screening of pharmaceutically or catalytically active ligands and receptors. The evaporation of bioactive volatiles that are emitted from flowers to attract insects and that are used as fragrances in our everyday life is limited in time. Dynamic mixtures obtained by reversible aminal formation of suitably designed diamines with volatile aldehydes prolong the perception of these compounds in functional perfumery.

Aminoalkyl-H-phosphinic acids, also called aminoalkylphosphonous acids, are investigated as biologically active analogues of carboxylic amino acids and/or as valuable intermediates for synthesis of other aminoalkylphosphorus acids. Their synthesis has been mostly accomplished by phospha-Mannich reaction of a P-H precursor, an aldehyde and an amine. The reaction is rarely clean and high-yielding. Here, reaction of H3PO2with secondary amines and formaldehyde in wet AcOH led to aminomethyl-H-phosphinic acids in nearly quantitative yields and with almost no by-products. Surprisingly, the reaction outcome depended on the basicity of the amines. Amines with pKa> 7-8 gave the desired products. For less basic amines, reductiveN-methylation coupled with oxidation of H3PO2to H3PO3became a relevant side reaction. Primary amines reacted less clearly and amino-bis(methyl-H-phosphinic acids) were obtained only for very basic amines. Reaction yields with higher aldehydes were lower. Unique carboxylic-phosphinic-phosphonic acids as well as poly(H-phosphinic acids) derived from polyamines were obtained. Synthetic usefulness of the aminoalkyl-H-phosphinic was illustrated in P-H bond oxidation and its addition to double bonds, and in selective amine deprotection. Compounds with an ethylene-diamine fragment,e.g.most common polyazamacrocycles, are not suitable substrates. The X-ray solid-state structures of seventeen aminoalkyl-phosphinic acids were determined. In the reaction mechanism,N-hydroxyalkyl species R2NCH2OH and [R2N(CH2OH)2]+, probably stabilized as acetate esters, are suggested as the reactive intermediates. This mechanism is an alternative one to the known phospha-Mannich reaction mechanisms. The conditions can be utilized in syntheses of various aminoalkylphosphorus compounds.

Human myeloperoxidase (MPO) plays an important role in innate immunity but also aggravates tissue damage by oxidation of biomolecules at sites of inflammation. As a result from a recent high-throughput virtual screening approach for MPO inhibitors, bis-2,2?-[(dihydro-1,3(2H,4H) pyrimidinediyl)bis(methylene)]phenol was detected as a promising lead compound for inhibition of the MPO-typical two-electron oxidation of chloride to hypochlorous acid (IC50= 0.5 muM). In the present pharmacomodulation study, 37 derivatives of this lead compound were designed and synthesized driven by comprehensive docking studies and the impact on the chlorination activity of MPO. We describe the structural requirements for optimum (i) binding to the heme periphery and (ii) inhibition capacity. Finally, the best three inhibitors (bis-arylalkylamine derivatives) were probed for interaction with the MPO redox intermediates Compound I and Compound II. Determined apparent bimolecular rate constants together with determination of reduction potential and nucleophilicity of the selected compounds allowed us to propose a mechanism of inhibition. The best inhibitor was found to promote the accumulation of inactive form of MPO-Compound II and has IC50= 54 nM, demonstrating the successful approach of the drug design. Due to the similarity of ligand interactions between MPO and serotonine transporter, the selectivity of this inhibitor was also tested on the serotonin transporter providing a selectivity index of 14 (KiSERT/IC50MPO).

Reactivity control in the addition of N,N?-dialkylated 1,n-diamines to activated skipped diynes: Synthesis of fused bicyclic 1,4-diazepanes and 1,5-diazocanes

A metal-free domino reaction for the synthesis of a new family of fused bicyclic 1,4-diazepanes and 1,5-diazocanes has been developed. The reaction involves the use of N,N?-dialkylated 1,n-diamines as the nitrogen source, through-space orbital interactions between the two nitrogen atoms as the reactivity director element, and an activated skipped diyne as the reactive platform. A key Morita-Baylis-Hillman-like reaction allows the formation of 1,4-diazepanes and 1,5-diazocanes (medium-sized diazoheterocycles). These structures incorporate a 1,n-diazocycle fused to a I3-butenolide ring and different functionalities to be used as convenient handles for further complexity generation. The good efficiency of this reaction and its simple experimental protocol make this process an excellent candidate for the fast construction of structure-focused libraries based on this fused bicyclic motif.

Synthesis and investigation of new cyclic haloamidinium salts

The presented work describes the synthesis of new six- and seven-membered haloamidinium salts and their reaction with different metals. The isolated metal complexes were tested in a catalytic reaction. Two different synthetic routes were applied to prepare five different salts. Chloroamidinium salts were very water-sensitive in comparison to their corresponding bromoamidinium salts. Hence, the preparation of the less sensitive bromoamidinium salts was higher prioritized. The formed salts were converted with metal sources to N-heterocyclic carbene (NHC) metal complexes through an oxidative insertion into the C-X bond. This type of formation is less examined for the synthesis of extended NHC metal complexes. Pd(PPh3)4 and cobalt powder were applied as metal sources, whereby two palladium complexes were isolated, characterized, and their crystal and molecular structures determined. The palladium complexes were investigated in the Suzuki-Miyaura reaction and showed promising catalytic activity.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Reference of 10239-34-6, you can also check out more blogs about10239-34-6
