摘要

An efficient methodology for the synthesis of 2, 2, 3-trisubstituted tetrahydroquinolines has been developed, which involves the triphenylphosphine–CCl4-mediated stereospecific rearrangement of α, α-disubstituted indoline-2-methanols to 2, 2, 3-trisubstituted tetrahydroquinolines. The rearrangement precursors are readily prepared by the diastereoselective Grignard addition to 2-acylindolines. The total syntheses of (+)- ...
