A biocatalytic/reductive etherification approach to substituted piperidinyl ethers

A synthetically useful protocol has been developed for the preparation of highly functionalized piperidinyl ethers. Biocatalytic reduction of cyclhexanones 7, 10, and 14 allows for the preparation of both cis- and trans diastereomers with an extremely high degree of stereochemical control. Reductive etherification of the corresponding trimethylsilylethers with 1-(benzyloxycarbonyl)-4-piperidinone 17 in the presence of triethylsilane and catalytic TMSO-Tf provides the desired piperidinyl ethers in good to excellent yields. Finally hygrogenolysis of the nitrogen protecting group leads to piperidinyl ethers in near quantitative yields. Application of the methodology to a range of piperidinyl ethers, including the core scaffolds of diphenylpyraline and ebastine, is also described.

Ouverture de dichlorocyclopropanes en presence d'un nucleophile interne. Absence de participation intramoleculaire. Rearrangement concerte en chlorures allyliques

It is shown that a conveniently placed internal nucleophile (carboxyl group) is not involved with the rearrangement of a diclorocyclopropane into an allylic chloride.This result appears to support a concerted mechanism of a ?s2 + ?a2 type for this rearrangement.In the products obtained, the allylic chloride may undergo displacement either by solvent (H2O), leading to alcohols, or by the internal carboxyl group, leading to a lactone.
