  描述：

  (2S)-N-[(4-oxocyclohex-1-enyl)methyl]tryptophan ethylene acetal methyl ester 在 偶氮二异丁腈 、 三正丁基氢锡 、 三乙胺 作用下， 以 二氯甲烷 、 苯 为溶剂， 反应 18.0h， 生成 2-[(1S)-2-(1H-indol-3-yl)-1-(methoxycarbonyl)ethyl]-2-aza-spiro[4,5]decan-3,8-dione ethylene acetal

  Synthesis of trans-perhydroisoquinolines by 6-endo-trig radical cyclization of amino-tethered vinyl bromides and cyclohexenes

  摘要：

  Bu3SnH-promoted cyclization of several N-(2-bromoprop-2-enyl)-N-[(4-oxocyclohex-l-enyl)methyl]alkylamines is reported. It has been found that the generated vinyl radicals evolve through a 6-endo-cyclization pathway giving rise to the corresponding 4,6-functionalized perhydroisoquinolines in a prevalent trans-relative configuration.
