The mevalonate pathway is an upstream terpenoid biosynthetic route of terpenoids for providing the two five-carbon units, dimethylallyl diphosphate, and isopentenyl diphosphate. Recently, trans-anhydromevalonate-5-phosphate (tAHMP) was isolated as a new biosynthetic intermediate of the archaeal mevalonate pathway. In this study, we would like to report the first synthesis of tAHMP and its enzymatic
甲羟戊酸途径是萜类的上游萜类生物合成途径,用于提供两个五碳单元,二甲基烯丙基二磷酸和异戊烯二磷酸。最近,反式-脱水甲羟戊酸-5-磷酸 (tAHMP) 作为古菌甲羟戊酸途径的一种新的生物合成中间体被分离出来。在这项研究中,我们想报告第一次合成 tAHMP 及其使用关键酶之一的酶促转化,甲羟戊酸 5-磷酸脱水酶来自超嗜热古细菌Aeropyrum pernix。从四甲基四乙酸甲酯开始,Cu 催化的烯丙基化以立体选择性的方式提供了E-三取代的烯烃。由此产生的Eα-烯烃通过烯烃的裂解和磷酸化转化为 tAHMP。合成 tAHMP 的结构由 NOESY 分析明确确定。
