Stereoselectivity in amidyl radical cyclisations. Acyl mode cyclisations
Clark, Andrew J.,Peacock, Joanne L.
, p. 6029 - 6032 (1998)
Amidyl radicals generated from tributylstannane mediated homolysis of O- benzoyl hydroxamic acid derivatives undergo 5-exo cyclisation to give mixtures of cis and trans pyrrolidinones. While the steric nature of the nitrogen substituents investigated had
Thoination of N-alkyl-O-acyl hydroxamic acid derivatives via Lawesson's reagent
Al-Faiyz, Yasair S. S.
, (2021/10/02)
N-alkyl-O-acyl thiohydroxamic acid derivatives were prepared in good yields by the treatment of their parent hydroxamic acids with Lawesson's reagent. Some of these thiohydroxamic acid derivatives exhibit the ability to undergo rearrangement under basic c

The first direct C-H β-trifluoromethylation of unsubstituted or α-alkyl-substituted α,β-unsaturated carbonyl compounds under metal-free conditions was realized with excellent regio- and stereoselectivity as well as a very broad substrate scope. Both olefi

An efficient copper-catalyzed electrophilic amination of benzoxazoles with O-benzoyl hydroxylamines is described, employing CuCl catalyst, PPh3 ligand, and LiOtBu base. This simple air-stable copper catalysis enables the preparation of various 2-aminobenzoxazole derivatives at room temperature in good yields.
