Diastereomerically pure 2-formyl-N-Boc-l,3-oxazolidine 7 was prepared in 83% yield from stannyloxazolidine 4. Grignard additions to the formyl group of compound 7 in the presence of Lewis acids afforded diastereomerically pure secondary carbinols 8. Protection of the hydroxyl group and unmasking of
Protected S-pyroglutamic acid can be deprotonated specifically at the y-position. The resulting enolate can be converted into y-carboxyglutamic acid in optically pure form. The naturally occurring aminoacid r\_carboxyglutamtc acid (1; Gla) is a constituent of prothrombin and other proteins.1 The nat
