Treatment of 1,2-dibromoalkanes with DBU effected an elimination reaction, leading to the alkynes. Oxygen substitution at the C3 position plays a critical role to abstract protons by inductive effects. By the application of this protocol, a total synthesis of sapinofuranone B 4 was accomplished.
用DBU处理1,2-二溴烷烃进行消除反应,生成炔烃。C3位置的氧取代对于通过感应效应提取质子起着至关重要的作用。通过该方案的应用,完成了番木瓜呋喃酮B 4的全合成。
