Asymmetric functionalization of a chiral non-racemic oxazolidine ester enolate.A new route towards the preparation of quaternary serine esters

摘要

A new route towards the preparation of a chiral non-racemic oxazolidine ester enolate.A new route towards the preparation of quaternary serine esters is described.The key step involves the diastereoselctive functionalization of an oxazolidine ester enolate having an exocyclic chiral appendage.
