Schizostatin (1) has been isolated as a potent and selective inhibitor of squalene synthase. Its structure has been determined using spectroscopic methods: the compound is shown to be a diterpenoid which has a trans-dicarboxylic acid moiety. Total synthesis of schizostatin (1) was achieved by the highly regio- and stereoselective coupling reaction of an allylic bromide with a barium reagent. The Z-isomer
Schizostatin(1)已被分离为角鲨烯合酶的有效和选择性抑制剂。它的结构已使用光谱法确定:该化合物显示为具有反式二羧酸部分的二萜类化合物。通过烯丙基溴与钡试剂的高度区域选择性和立体选择性偶合反应,可实现schizostatin(1)的全合成。Z-异构体16也使用有机铜试剂向乙炔二羧酸酯的立体选择性顺式加成制备。
