参考标题:A New Approach To The Synthesis Of 1-Oxaspiro[4.N]Alkanes And Tetrahydrofurans By The 1,5-Ch Insertion Reaction Of Magnesium Carbenoids 作者:Tsuyoshi Satoh,Tsukasa Yasoshima,Hitoshi Momochi |发布日期:2012.4 摘要:In High To Quantitative Yields Via The 1,5-Ch Insertion Reaction Of Generated Magnesium Carbenoid Intermediates. When This Procedure Was Commenced With Acyclic Ketones, Multi-Substituted Tetrahydrofurans Were Obtained In Up To A 96% Yield. This Procedure Provides A New And Good Way For The Synthesis Of 1-Oxaspiro[4.N]Alkanes And Tetrahydrofurans With The Formation Of A Carbon-Carbon Bond Between A Carbenoid
