The total synthesis of aculeatins A, B, E and F confirming the assigned absolute configuration of recently isolated aculeatins E and F is documented. A convergent approach has been designed by the addition of both the terminal units (phenol and side chain) at an advanced stage. The central 1,3,5-triol unit with the requisite stereochemistry was prepared from the commercially available α-d-glucoheptonic-γ-lactone
记录了aculeatins A,B,E和F的总合成,证实了最近分离出的aculeatins E和F的指定绝对构型。通过在高级阶段同时添加两个末端单元(苯酚和侧链),已设计出一种收敛方法。由市售的α - d-葡庚七酮-γ-内酯制备具有必要立体化学的中心1,3,5-三醇单元。二炔中间体的氢解过程中的选择性O-脱苄基反应以及伴随螺环化的一锅酚氧化反应突出了已完成的总合成过程。
