The results reported seem to indicate, that in the presence o: a nucleophilic base intramolecular alkylation is the normal reaction mode of tosyloxymethylcyclanones of type 14 and that the fragmentation reaction of five-membered compounds is the exception, probably because of the high steric energy of the alkylation transition states, e.g. of type E.
报告的结果似乎表明,在以下条件下存在:亲核碱基分子内烷基化是14型甲苯磺酰氧基甲基环烷的正常反应方式,五元化合物的片段化反应是一个例外,可能是由于烷基化过渡状态,例如类型的ë。
