Zeng, Xiaojun; Yan, Wenhao; Zacate, Samson B.; Cai, Aijie; Wang, Yufei; Yang, Dongqi; Yang, Kundi; Liu, Wei published the artcile< Copper-Catalyzed Deaminative Difluoromethylation>, SDS of cas: 3731-53-1, the main research area is copper catalyst deaminative difluoromethylation alkyl amine; copper; deamination; difluoromethylation; homogeneous catalysis; pyridinium salts.
The difluoromethyl group (CF2H) is considered to be a lipophilic and metabolically stable bioisostere of an amino (NH2) group. Therefore, methods that can rapidly convert an NH2 group into a CF2H group would be of great value to medicinal chem. The authors report herein an efficient Cu-catalyzed approach for the conversion of alkyl pyridinium salts, which can be readily synthesized from the corresponding alkyl amines, to their alkyl difluoromethane analogs. This method tolerates a broad range of functional groups and can be applied to the late-stage modification of complex amino-containing pharmaceuticals.
