The chirality of the 3-hydroxy-3-methylglutaric acid (HMGA) moiety of fasciculic acid A (1), a calmodulin antagonist isolated from Naematoloma fasciculare, was established to be S by comparing the 1H-NMR spectrum of the L-alanylamide of HMGA derived from 1 with those of its diastereomer and the diastereomeric mixture.
通过比较从筋膜瘤(Naematoloma fasciculare)中分离出的钙调素拮抗剂筋膜瘤酸甲(1)中 HMGA 的 L-丙氨酰酰胺的 1H-NMR 光谱及其非对映异构体和非对映异构体混合物的 1H-NMR 光谱,确定了筋膜瘤酸甲(1)的 3-羟基-3-甲基戊二酸(HMGA)分子的手性为 S。
