(4R)-4-amino-2-penten-5-olide and to protected (2S)- and (2R)-3-dehydro-2-hydroxymethyl-5-pyrrolidone. The β-methallyl- and β-isobutylglutamic acids were also synthesized in a similar manner. The depolarizing activities of these synthesized compounds were observed.
β-苄基谷
氨酸的四种立体异构体是通过将苄基苯
硫醚迈克尔加成到受保护的(4 S)-和(4 R)-4-
氨基-
2-戊烯5-内酰胺以及受保护的(2 S)-和( 2 R)-3-脱氢-2-羟甲基-5-
吡咯烷酮。β-甲基烯丙基-和β-异丁基谷
氨酸也以类似方式合成。观察到这些合成化合物的去极化活性。
