On treatment with BF3·OEt2 and TMSCN, epoxy ketone 1 cyclized to the bicyclic acetal 2, which then cleaved to give primarily the oxepane 5 as a single stereoisomer. Reductive decyanation of 5 led to the oxepane 7, a structural unit present in the brevetoxin family of natural products. The scope and limitations of this reaction sequence were investigated.
用BF 3 ·OEt 2和TMSCN处理后,环氧酮1环化成双环缩醛2,然后裂解产生环氧丙烷5,为单一立体异构体。5的还原性脱氰作用导致产生环氧丙烷7,环氧丙烷7是天然产品短毒素家族中的一个结构单元。研究了该反应顺序的范围和局限性。
