We describe here a convenient and mild procedure for double carbonylation of o-dibromobenzenes with various 2-amino pyridines and naturally occurring amines, thus providing in good to excellent yields N-substituted phthalimides by using this palladium-catalyzed carbonylation procedure. Furthermore, for the first time we have applied the developed synthetic protocol for the synthesis of biologically active molecule thalidomide via a single step carbonylative cyclization reaction in excellent yield. the Partner Organisations 2014.
Interrupting the Barton?McCombie reaction: Aqueous deoxygenative trifluoromethylation of o-alkyl thiocarbonates
Liu, Zhi-Yun,Cook, Silas P.
, p. 808 - 813 (2021/02/01)
The site-selective trifluoromethylation of aliphatic systems remains an important challenge. This work describes a light-driven, copper-mediated trifluoromethylation of O-alkyl thiocarbonates. The reaction provides broad functional group tolerance (e.g., alkyne, alkene, phenol, free alcohol, electron-rich and -deficient arenes), thereby offering orthogonality and practicality for trifluoromethylation. A radical organometallic mechanism is proposed.
