Exclusive 1,6-cyclization occurred to afford isoquinoline frameworks when the enamide and the enamine substrates bearing exo-olefin moiety were treated with tri-n-butyltin hydride in the presence of radical initiator (9a, b → 12a, b; 13a, b → 18a, b), respectively. On the other hand, competitive 1,6- and 1,5-cyclization occurred to give a mixture of isoquinolone and isoindolone frameworks when the enamide
发生独家1,6-环化,得到当烯酰胺和带有烯胺底物异喹啉框架外的α-烯烃部分用三-处理Ñ在自由基引发剂(存在-butyltin氢化9A,B →图12A,B ; 13A,B → 18a,b)。另一方面,当在相同条件下(22a,b → 26a,b和26)处理带有内烯烃部分的酰胺底物时,竞争性的1,6-和1,5-环化反应产生了异喹诺酮和异吲哚酮骨架的混合物。27a,b)。
