Aldol replacement: Catalyticasymmetric ketene–aldehyde cycloadditions provide surrogates for traditional aldol additions in an enantioselectivesynthesis of apoptolidinone C, the aglycone of the potent apoptosis regulator apoptolidinC. Eight of apoptolidinone C's ten stereocenters derive directly from these catalytic acetate or propionate aldolequivalents.
羟醛替代:催化不对称烯酮-醛环加成在对映选择性合成阿朴烷酮 C(有效凋亡调节剂 apoptolidin C 的苷元)中提供了传统羟醛加成的替代物。阿朴烯酮 C 的 10 个立体中心中有 8 个直接来自这些催化乙酸酯或丙酸醛醇等价物。
