Abstract

Starting from a suitably functionalized aziridine, a highly efficient stereoselective synthesis of (1R,2R)-phenyl-2-decanoyl­amino-3-morpholinopropan-1-ol (d-threo-PDMP) is described. The approach, based on the ring expansion of the aziridine ring to oxazoline, could be applicable to the synthesis of many analogues with different amide chains and sugar mimic portions.

Key words

regioselectivity - ring opening - glycosidases - inhibitors - ring expansion
