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 15 to 2,2,3-trisubstituted tetrahydroquinolines 26. The rearrangement precursors 15 are readily prepared by the diastereoselective Grignard addition to 2-acylindolines 13. The total syntheses of (+)-benzastatin
