A rapid convergent strategy to access unsaturated analogues of peloruside A has been demonstrated. This is depicted as an original C11-C12 aldol connection between a C12-C20 ketone fragment and a C2-C11 pyran fragment bearing an aldehyde function, with high yield and a good level of diastereoselectivity. The desired unsaturated macrocycle was obtained by a late-stage ring closing metathesis reaction
已经证明了一种获取 peloruside A 的不饱和类似物的快速收敛策略。这被描述为 C12-C20 酮片段和带有醛官能团的 C2-C11 吡喃片段之间的原始 C11-C12 醛醇连接,具有高产率和良好的非对映选择性。通过后期闭环复分解反应获得所需的不饱和大环。
