Unreactive CH to attractive CN: A palladium‐catalyzed intramolecular direct amidation of unactivated C(sp3)Hbonds combines CH activation and CN bond formation into one efficient process. Under the optimized conditions, an extraordinary tolerance of functional groups was observed, and numerous indoline derivatives were formed (see scheme).
the reaction of allyl acetate with the anionic species prepared from various N-(2-tert-butylphenyl)sulfonamides and NaH proceeded in an enantioselective manner (up to 95% ee) to give optically active N-allylated sulfonamide derivatives possessing an N–C axially chiral structure in high yields.
