Both enantiomers of (S) 1 and (R) 2 isoserine as well (D) 3 and (L) 4 allothreonine are prepared optically pure in three steps by asymmetric Sharpless epoxidation of crotyl and allylic alcohols into 7-10 followed by an improved RuCl3/NaIO4/water oxidation procedure to low molecular weight glycidic acids 11-14 and epoxide opening by ammonia with (20-33 percent) overall yields.
