THE REACTION OF DICHLOROCARBENE WITH β-ETHANOLAMINES. STEREOSPECIFIC SYNTHESIS OF EPOXIDES
Castedo, Luis,Castro, Jose L.,Riguera, Ricardo
, p. 1205 - 1208 (1984)
Optically pure β-ethanolamines were converted into epoxides in good yield and with high e.e. (>= 95percent) by reaction with dichlorocarbene.By this method α-aminoacids were successfully converted into synthetically useful epoxides.
