The stereoselective total syntheses of botcinic acid, botcinic acid methyl ester, 3-O-acetylbotcinic acid methyl ester, botcineric acid, and botcinin E were achieved. The structures of these compounds have been unequivocally determined through their total synthesis, and they are identified with the revised structures of botcinolide, 4-O-methylbotcinolide, 3-O-acetyl-5-O-methylbotcinolide, homobotcinolide
得到了立体选择性的植物酸,植物酸甲酯,3- O-乙酰基植物酸甲酯,植物酸和植物素E的全合成。这些化合物的结构已通过它们的全合成明确确定,并已通过肉毒杆菌内酯,4- O-甲基肉毒酚,3- O-乙酰基-5- O-甲基肉毒杆菌素,高肉毒酚和2-表肉毒酚内酯的修饰结构进行鉴定,分别。
