描述了一种简洁的立体选择性合成的三氧二旋酮基序,该基序体现了海洋大环内酯(+)-螺螺醇内酯A的def环。该合成方法的特点是一系列的环缩醛拴环闭合复分解和Suárez氧化环化,从而构成了构建北半部分的可行策略。
A concise and stereoselective synthesis of the trioxadispiroketal motif that embodies the DEF-ring of the marine macrolide (+)-spirastrellolide A is described. The synthetic approach features a sequence of cyclic acetal tethered ring-closing metathesis and Suárez oxidative cyclization, thereby constituting a viable strategy for constructing the Northern Half.
