Abstract

In the course of our research program directed towards the study of new allenyl copper reagents, we focused on these reactions to obtain analytical samples suitable for structure determinations as well as multi-gram amounts of chiral inductors such as enantiopure oxazolidinone 1. A practical synthesis of oxazolidinone 1 reported by Davies began with the addition of excess PhMgBr to α-amino methyl ester 2 to afford the corresponding aminoalcohol 3, followed by a ring- ...
