Thioamide and Thioester Cyclopentane Synthesis via Trimethyltin Radical Catalyzed Alkenylation of Substituted (Thiocarbonyl)cyclopropanes
摘要:
Thioamide cyclopropanes bearing phenyl substituents and thioamide- or thioester cyclopropanes bearing gem-dichloro and methyl substituents were subjected to trimethyltin radical catalyzed alkenylation to furnish the corresponding substituted (thiocarbonyl)cyclopentanes. The stereochemical outcome of these transformations can be rationalized by considering the effects of substituents, upon cyclization of the intermediate functionalized 5-hexenyl radicals.
