Journal ArticleDOI
Recent Progress in the Generation and Use of Nitrogen‐Centered Radicals
Journal ArticleDOI
Synthesis of Substituted 4-Arylpiperidin-2-ones by a 6-exo-Trig Radical Cyclization
Xavier Vila,Samir Z. Zard +1 more
TL;DR: A series of 5-substituted-4-arylpiperidin-2-ones have been synthesized in a 4-step sequence involving a radical 6-exo-trig cyclization as the key step.
Journal ArticleDOI
Novel route to triethylsilyl-substituted cyclopropanes.
Shi-Guang Li,Samir Z. Zard +1 more
TL;DR: The sequence works best with phenacyl type adducts, and the use of the less bulky trimethysilyl (TMS) derivatives results in extensive desilylation.
Journal ArticleDOI
A convergent, modular access to α-chloro-trifluoromethyl derivatives and to 1,1-difluoroalkenes
TL;DR: In this paper, an efficient protocol for the preparation of S -(1-chloro-2, 2,2,2-trifluoroethyl)-O -ethyl xanthate is reported.
Journal ArticleDOI
A versatile radical based approach to O-alkylated hydroxylamines and oximes
TL;DR: In the case of N -Boc- O -allylhydroxylamine, the addition is unexpectedly followed by elimination resulting in an overall allylation of the radical species.
