摘要：
The dual alkylation of the C(sp(3))-H bond of cyclic alpha-methyl-N-sulfonyl imines has been achieved through the piperidine-promoted cascade condensation/[1,5]-hydride transfer/cyclization sequence from cyclic alpha-methyl-N-sulfonyl imines and o-aminobenzaldehydes in trifluoroethanol, providing structurally diverse 3-cyclic N-sulfonyl imine substituted tetrahydroquinolines in good yields with excellent diastereoselectivities.
