Abstract

In the framework of the approach to remote oxidative functionalization of organic compounds of various classes, which is currently under exploration by us and which is based on reactions of element-centred free radicals, the regiospecific oxidative cyclization of N- methylsulfonylalkylamines 3 into N-methylsulfonylpyrrolidines 4 has been accomplished. The more facile isomerisation of intermediate sulfonamidyl radicals 8 with 1, 5-H shift in ...
