| Abstract: | Efficient syntheses of 3,4-diarylsubstituted hexahydro-1H-indoles in good yields with excellent diastereoselectivities were achieved with a two-step protocol comprising an allylic cation mediated nucleophilic addition and an intramolecular cyclization reaction. The N-aryl sulfonyl protecting groups of cyclization products were readily removed to furnish free amines with retention of halogen substitutions and C | |
