Benzyl dialkyl phosphates are deprotonated enantioselec-up to 50%. The pro-(S) hydrogen is removed by amides hatively by homochiral lithium amides of isopropyl( 1-phenyl-ving (S) configuration. Homochiral diethyl (S)-phenyl[D+ ethy1)amine or bis(1-phenylethy1)amine. The short-lived ben-methyl phosph
