butenolides as substrates in the electroreductive cyclization reaction has been investigated. A variety of butenolides bearing either an α,β,-unsaturated ester, an α,β,δ,-unsaturated ester, allylic bromide, bromide, mesylate or aldehyde functionality on the appending side chain have been examined. The performance of each of these systems under electroreductive cyclization reaction conditions is severely limited
已经研究了丁烯内酯在电还原环化反应中作为底物的潜在用途。已经研究了在附接的侧链上带有α,β,不饱和酯,α,β,δ,不饱和酯,烯丙基溴,溴化物,甲磺酸酯或醛官能度的各种丁烯化物。这些系统在电还原环化反应条件下的性能受到丁烯内酯环的C5和附加侧链的C1处酸性质子的存在的严重限制。
