  N-Acyl-N-alkylcarbamoyloxy radicals: Entries to amidyl radicals by decar☐ylation and to α-amide radicals by radical translocation

  摘要：

  N'-Acyl-N-hydroxypyridine-2-thione carbamates react in radical chain reactions to give the title radicals which can decarboxylate or react by intramolecular hydrogen atom transfer; the competing reaction pathways are controlled by the structure of the alkyl group and the conformation of the precursor which can be influenced by addition of a Lewis acid.

  N-Acyl-N-alkyl-N'-hydroxypyridine-2-thione carbamates (N-acyl PTOC carbamates) 1 are prepared in good to excellent yield by reactions of N-acylcarbamoyl chlorides with N-hydroxypyridine-2-thione sodium salt. Methods for production of the requisite carbamoyl chlorides by reaction of a secondary amide with trimethylsilyl triflate followed by treatment with phosgene were optimized. Precursors 1 react in radical chain reactions to give the title radicals (2) that can further react by several pathways. Decarboxylations of radicals 2 give amidyl radicals, and this method is excellent for production of acetamidyl radicals and in particular the N-methylacetarnidyl radical which is difficult to prepare by other routes. 5-Exo cyclizations of amidyl radicals produced by decarboxylation of 2 give, ultimately, lactams and N-acylpyrrolidines. 1,5-Hydrogen transfer reactions of 2 to give alpha-amide radicals compete with decarboxylation; cyclization of an alpha-amide radical thus formed also is reported. The Lewis acid MgBr2 can reduce the 1,5-hydrogen atom transfer reaction apparently by a chelation effect on the precursor that leads to production of radical 2 in a conformation unfavorable for hydrogen atom transfer. By appropriate experimental design, radicals 2 often can be directed toward one desired reaction, and several relative rate constants for reactions of 2 necessary for such design were determined in this work.
