A chiral-pool approach for the construction of methylene bis-tetrahydropyran subunit, C1–C16 fragment, of (−)-exiguolide is described. The synthesis was efficiently accomplished starting from l-glutamic acid and l-aspartic acid involving oxa-Michael reaction and an aldol-driven-reductive etherification as key steps for the formation of tetrahydropyran ring.
描述了一种手性池方法,该方法用于构建(-)-exiguolide的亚甲基双-四氢吡喃亚基,C 1 -C 16片段。从1-谷氨酸和1-天冬氨酸开始的合成有效地完成,所述1-谷氨酸和1-天冬氨酸涉及形成四氢吡喃环的关键步骤的氧杂-迈克尔反应和羟醛驱动的还原性醚化反应。
