Synthetic Route to Chiral Indolines via Ring-Opening/C–N Cyclization of Activated 2-Haloarylaziridines
摘要:
A practical approach for the synthesis of 3-substituted indolines via regio- and stereoselective S(N)2-type ring opening of 2-(2-halophenyl)-N-tosylaziridines with heteroatomic nucleophiles (O, N, and S) followed by palladium catalyzed intramolecular C-N cyclization is reported in excellent yields (up to >99%) and enantiomeric excess (ee 99%)
