Mapping the stereochemical course of carbonyl phosphonylation via chiral phosphorodiamidites
摘要:
The asymmetric phosphonylation of aldehydes via chiral phosphorodiamidites has been examined as a function of the steric profile of the chiral auxiliary employed. Comparison of N-Me and N-Pr-i-(1R,2S)-ephedrine auxiliaries reveals that the latter results in a consistently stronger preference for (S-P,S-C) product stereochemistry than the former.
