A new synthesis of the tetrasubstituted tetrahydrofuran fragment of the marine secondary metabolites amphidinolides X and Y is described. The oxygenated chiral quaternary carbon was assembled by asymmetric dihydroxylation in high enantioselectivity and the tetrahydrofuran ring was constructed by an acid-catalyzed 5-endo ring-opening cyclization of the epoxide possessing a vinyl moiety.
描述了海洋次生代谢物 amphidinolides X 和 Y 的四取代四氢呋喃片段的新合成。氧化手性季碳是通过不对称二羟基化以高对映选择性组装的,四氢呋喃环是通过酸催化的具有乙烯基部分的环氧化物的 5-内开环环化来构建的。
