Lipase behavior in the stereoselective transesterification of zingerol-like derivatives and related biphenyls

Using a highly stereoselective enzymatic procedure based on the irreversible transesterification of alcoholic functions in organic solvent, both enantiomers of zingerol and dehydrozingerol O-methyl derivatives 1 and 2 were obtained in high optical purity. The biocatalytic method was then extended to the corresponding biphenyl derivatives 5-8 for which an one-pot resolution/desymmetrization was carried out on the whole racemic/meso mixtures to give single stereoisomers with very high enantiomeric and diastereoisomeric excesses. The comparison of kinetic and enantioselective behavior of the lipase AK from Pseudomonas fluorescens in the transesterification of monomer (±)-1 and the related (±)-5 and meso-6 biphenyl dimers was also made.

Hypervalent iodine(III)-induced intramolecular cyclization reaction of substituted phenol ethers with an alkyl azido side-chain: A novel and efficient synthesis of quinone imine derivatives

Novel and efficient syntheses of quinone imine ketals (2aj) and quinone imines (4ah) from substituted phenol ethers (1ak) bearing an alkyl azido side-chain using the combination of hypervalent iodine(III) reagent, phenyliodine(III) bis(trifluoroacetate) (PIFA) and trimethylsilyl trifluoromethanesulfonate (TMSOTf), have been developed.

Ortho-effects in 1-(2-Aminomethylaryl)-1-buten-3-ones and Their Hydrogenation Products, III: 2-(Aminomethyl)phenylmethylenacetones and Their Hydrogenation Products, II

The preparations of the phenylmethylenacetones and their (deuterated) hydrogenation products (compounds 2-28) are described; anomalies in some of the (13)C-NMR spectra are explained by increment calculations.
