Synthesis of quaternary α-perfluoroalkyl lactams via electrophilic perfluoroalkylation†
Abstract
Efficient protocols enabling the rapid installation of trifluoromethyl, as well as further functionalized fluoroalkyl groups by an electrophilic perfluoroalkylation of lactam-derived ketene silyl amides (KSAs) using hypervalent iodine reagents 1 and 2 have been developed.
