the initial stereochemical information is central to the efficient and highly stereocontrolled construction of the C1-C15 fragment of the marine macrolide leucascandrolide A. Cyclic silane 3, assembled via Pt-catalyzed hydrosilylation, was designed to serve as a temporary template for the installation of the C12 stereogenic center. The strategy features a highly convergent C10-C11 bond construction
[结构:见文字]。初始立体化学信息的完整传递对于海洋大环内酯类白屈内酯A的C1-C15片段的高效且高度立体控制的构建至关重要。通过Pt催化的氢化硅烷化反应组装的环硅烷3可作为以下化合物的临时模板C12立体音响中心的安装。该策略的特点是通过1,5-抗选择性醛醇缩合反应实现高度收敛的C10-C11键构建,并通过Prins非对称化快速组装三取代的吡喃亚基。
