✦ Synopsis

Regioselective Dieckmann Cyclizations Leading to Enantiopure Highly Functionalized Tetramic Acid Derivatives.

-Regioselective Dieckmann cyclizations of N-acyloxazolidines (III) derived from L-serine give substituted tetramic acids in high yields and enantioselectivity. The products are easily deprotected under mild conditions to give hydroxymethyltetramic acids [cf. (VI), (VII)]. -(ANDREWS, M.
