The first vinylogous Mukaiyama aldol reactions with tris(pentafluorophenyl)borane and triphenylborane are described. Both Lewis acids diastereoselectively generate the C19–C21 all-syn stereo triad of ratjadone, and in the case of tris(pentafluorophenyl)borane the reaction proceeds with substoichiometric amounts.
描述了与三(五氟苯基)硼烷和三苯基硼烷的第一个乙烯基Mukaiyama醛醇缩合反应。两种路易斯酸都非对映选择性地生成大鼠jajadone的C19-C21全顺式立体三联体,在三(五氟苯基)硼烷的情况下,反应以亚化学计量的量进行。
