A short highly efficient synthesis of the C3C16 fragment 2 of laulimalide 1 is described. Fragment 2 was a key intermediate in a previous approach and thus constitutes a formal total synthesis with improved efficiency. The key steps are an Evans’ alkylation, a Brown allylation and a chirally catalysed stereocontrolled ene-reaction.
描述了劳来那肽1的C3C16片段2的短时高效合成。片段2是先前方法中的关键中间体,因此构成了具有改进效率的正式总合成。关键步骤是埃文斯烷基化,布朗烯丙基化和手性催化的立体控制烯反应。
