Asymmetric synthesis of 2,3-dimethoxy-8-oxoberbine, precursor of 0-methylbharatamine

The enantiospecific and enantioselective syntheses of 2,3-dimethoxy-8-oxoberbine were performed using the lateral retaliation methodology. In the enantiospecific synthesis (4S)-2,2,4-trimethyl-3-(o-toluoyl)-oxazolidine incorporating (S)-alaninol as the chiral auxiliary was applied. The addition reaction of benzylic anion generated in situ from chiral oxazolidine into 6,7-dimethoxy-3,4-dihydroisoquinoline led to the protoberberine with high enantiomeric excess. Enantioselective synthesis of 2,3-dimethoxy-8-oxoberbine was performed with achiral 2,2-dimethyl-3-(o-toluoyl)oxazolidine in the presence of chiral ligands. Among them (-)-sparteine and (+)-sparteine surrogate turned out to be the most efficient ones.

(S)-proline-derived catalysts for the acylative kinetic resolution of alcohols: A remote structural change allows a complete selectivity switch

A systematic preliminary study has identified a suite of catalysts, all readily prepared and derived from (S)-proline, which differ by a remote substituent only. If this substituent is capable of hydrogen-bond donation the catalyst will promote the resolution of secondary alcohols with the opposite sense of enantiodiscrimination to that observed when the substituent is capable of accepting hydrogen bonds.

Stereospecific, Nickel-Catalyzed Suzuki-Miyaura Cross-Coupling of Allylic Pivalates to Deliver Quaternary Stereocenters

Recognizing the importance of all-carbon, quaternary stereocenters in complex molecule synthesis, a stereospecific, nickel-catalyzed cross-coupling of allylic pivalates with arylboroxines to deliver products equipped with quaternary stereocenters and internal alkenes was developed. The enantioenriched allylic pivalate starting materials are readily prepared, and a variety of functional groups can be incorporated on both the allylic pivalate and the arylboroxine. Additional advantages include the use of a commercially available and air-stable Ni(II) salt and BISBI ligand, mild reaction conditions, and high yields and ee’s. The observed stereoinversion of this reaction is consistent with an open transition state in the oxidative addition step.

Empirical method for predicting enantioselectivity in catalytic reactions: demonstration with lipase and oxazaborolidine

We derived a novel equation capable of predicting the degree of enantioselectivity in a catalytic reaction without any knowledge of the reaction mechanism and/or the transition-state structure, and tested the validity of this equation by changing substrates systematically in the lipase or oxazaborolidine-catalyzed reactions. A good correlation was observed between the predicted and observed E values, and the stereochemistry of the products could be predicted correctly in most cases (28 out of 30).

An enantioselective approach to cytotoxic norcalamenenes via electron-transfer-driven benzylic umpolung of an arene tricarbonyl chromium complex

An efficient enantioselective total synthesis of (R)-1-isopropenyl-6-methoxy-7-methyl-1,2,3,4-tetrahydronaphthalene, the dehydro-analog of the cytotoxic norsesquiterpene (R)-7-demethyl-2-methoxycalamenene, was achieved in seven steps starting from 6-methoxytetralone. The synthesis exploits the specific reactivity and stereochemistry of planar chiral eta6-arene-Cr(CO)3 complexes. In a key step, a Cr(CO)3-complexed benzylic anion, regioselectively generated by means of electron- transfer-driven benzylic umpolung, is diastereoselectively alkylated with acetyl chloride.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 112068-01-6 is helpful to your research. Recommanded Product: 112068-01-6

Modular synthesis of cyclic cis- and trans-1,2-diamine derivatives

Structurally diverse carbocycles with two vicinal nitrogen-substituents were prepared in expedient three-component reactions from simple amines, aldehydes, and nitroalkenes. trans,trans-6-Nitrocyclohex-2-enyl amines were obtained in a one-pot domino reaction involving condensation, tautomerisation, conjugate addition, and nitro-Mannich cyclisation. Upon employment of less nucleophilic carboxamides, a concerted Diels-Alder cycloaddition mechanism operated to give the corresponding cis,trans-nitrocyclohexenyl amides. Both types of substituted carbocycles offer ample opportunities for chemical manipulations at the core and periphery. Ring oxidation with MnO2 affords substituted nitroarenes. Reduction with Zn/HCl provides access to various trans- and cis-diaminocyclohexenes, respectively, in a straight-forward manner. With enantiopure secondary amines, a two-step synthesis of chiral nitrocyclohexadienes was developed (82-94% ee).
