Amano PS lipase catalyzes the reaction of formic hydrazide, acetic hydrazide and methyl carbazate with various esters: α, β-unsaturated hydrazides were obtained by using methyl acrylate or vinyl crotonate. The reaction with ethyl (±)-2-chloropropionate yields the corresponding hydrazide in good yield but with moderate enantiomeric excess.
Amano PS 脂肪酶催化甲酸肼、醋酸肼和甲基氨基甲酸酯与各种酯的反应:使用丙烯酸甲酯或乙烯基克罗托酸酯可以获得 α,β-不饱和肼。与乙基 (±)-2-氯丙酸酯的反应可产生相应的肼,产率良好,但手性过剩中等。
