Procyanidin oligomers. A new method for 4?8 interflavan bond formation using C8-boronic acids and iterative oligomer synthesis through a boron-protection strategy

Interest in the synthesis of procyanidin (catechin or epicatechin) oligomers that contain the 4?8 interflavan linkage remains high, principally due to research into their health effects. A novel coupling utilising a C8-boronic acid as a directing group was developed in the synthesis of natural procyanidin B3 (i.e., 3,4-trans-(+)-catechin-4alpha?8-(+)- catechin dimer). The key interflavan bond was forged using a novel Lewis acid-promoted coupling of C4-ether 6 with C8-boronic acid 16 to provide the alpha-linked dimer with high diastereoselectivity. Through the use of a boron protecting group, the new coupling procedure was extended to the synthesis of a protected procyanidin trimer analogous to natural procyanidin C2.

Expanding the medicinal chemistry synthetic toolbox

The key objectives of medicinal chemistry are to efficiently design and synthesize bioactive compounds that have the potential to become safe and efficacious drugs. Most medicinal chemistry programmes rely on screening compound collections populated by a range of molecules derived from a set of known and robust chemistry reactions. Analysis of the role of synthetic organic chemistry in subsequent hit and lead optimization efforts suggests that only a few reactions dominate. Thus, the uptake of new synthetic methodologies in drug discovery is limited. Starting from the known limitations of reaction parameters, synthesis design tools, synthetic strategies and innovative chemistries, here we highlight opportunities for the expansion of the medicinal chemists? synthetic toolbox. More intense crosstalk between synthetic and medicinal chemists in industry and academia should enable enhanced impact of new methodologies in future drug discovery.

Extending the family of N-heterocyclic heavy carbene analogues: Synthesis and crystal and molecular structures of MeN[CH2C(O)N(R)] 2Sn (R = Me2NCH2CH2, PhCH 2, Me3CCH2)

We report herein the synthesis of the N-methyl-N?N?- diorganoiminodiacetic acid diamides MeN[CH2C(O)N(R)H]2 [3: R = Me2N(CH2)2; 4: R = PhCH2; 5: R = Me3CCH2] and the novel tin(II) derivatives MeN[CH 2C(O)N(R)]2Sn [6: R = Me2N(CH2) 2; 7: R = PhCH2; 8: R = Me3CCH2]. The compounds were characterized by elemental analyses, 1H NMR spectroscopy (3-5), solid-state 13C and 119Sn NMR spectroscopy (8), and single-crystal X-ray diffraction analysis (5, 8). Compound 8 shows intramolecular N?Sn and intermolecular O?Sn interactions with distances of 2.370(2) and 2.406(2) A, respectively, the latter indicating that 8 is a coordination polymer. DFT calculations revealed covalent Sn-NC(O) and coordinative N?Sn and C=O?Sn bonds. The wB97Xd functional, which takes into account dispersive interactions, was employed for a correct theoretical description of, in particular, the latter bond. A novel type of intramolecularly coordinated N-heterocyclic diazastannylene is reported that holds great potential for subsequent chemistry due to its high stability in air and the many possibilities to vary the substituents.

Microwave-mediated synthesis of N-methyliminodiacetic acid (MIDA) boronates

A library of over 20, mainly aryl or heteroaryl, N-methyliminodiacetic acid (MIDA) boronates have been synthesised. A rapid microwave-mediated (MW) method (5-10 min) has been developed using polyethylene glycol 300 (PEG 300) as solvent. However, acetonitrile (MeCN) and dimethylformamide (DMF) were found to be alternative solvents, the latter especially for 2-substituted aryl boronic acids.

The effect of the central donor in bis(benzimidazole)-based cobalt catalysts for the selective cis-1,4-polymerisation of butadiene

A series of bis(benzimidazole)-based cobalt(II) dichloride complexes containing a range of different central donors has been synthesized and characterized. The nature of the central donor affects the binding of the ligand to the cobalt centre and determines the coordination geometry of the metal complexes. All complexes have been shown to catalyse the polymerization of butadiene, in combination with MAO as the co-catalyst, to give cis-1,4-polybutadiene with high selectivity. The nature of the central donor has a marked influence on the polymerization activity of the catalysts, but does not affect the polymer microstructure. The addition of PPh3 generally increases the polymerization activity of these cobalt catalysts and results in predominantly (60-70%) 1,2-vinyl-polybutadiene. The Royal Society of Chemistry 2010.
