Abstract

Camphor derived oxazoline-N-oxides in the presence of various acylating agents afforded α- acyloxyoxazolines resulting from a diastereoselective [3, 3] rearrangement. The configuration of the newly formed asymmetric center was established by chemical correlation. The observed diastereoselectivity accounts a concerted rather than a stepwise process.
