(2S,4R,5R)-3-Isopropyl-4-methyl-5-phenyl-2-(2-propenyl)-1,3, 2-oxazaphospholidin-2-one (1) was synthesized stereospecifically from (2R,4R,5R)-2-chloro-3-isopropyl-4-methyl-5-phenyl-1,3, 2-oxazaphospholidin-2-one (5) with allylmagnesium bromide or the diallylaluminum reagent, and its structure was verified by a single crystal X-ray analysis. The anion of 1 underwent exclusive stereoselective 1, 4-addition reaction with ethyl 3,4-dihydro-4-oxo-(2H)-pyridine-1-carboxylate (7).
