The intramolecular cyclization of an allyl halide having a carbonyl group proceeded smoothly via an allyl anion in the presence of Me3SiSnBu3 and CsF in DMF. The resultant products were converted into useful compounds for the synthesis of natural products.
在
DMF中Me3SiSnBu3和CsF存在下,具有羰基的烯丙基卤的分子内环化通过烯丙基阴离子顺利进行。所得产物被转化为合成
天然产物的有用化合物。
