Enantioselective functionalization of prochiral C–H bonds can potentially lead to a broad range of efficient routes to chiral compounds. Despite extensive efforts, the scope and efficiency of enantioselective C(sp 3)–H activation reactions are far from adequate for broad applications in asymmetric synthesis (1, 2).Enantioselective carbene and nitrene insertions into C(sp 3)–H bonds have

TOTAL SYNTHESIS OF CELOGENTIN C VIA A strategy which involved an NCS-mediated oxidative C-N σ bond formation of the Trp-C2 of intermediate 137 with the His-N1 of an Arg/His dipeptide. The right-hand ring of the natural product celogentin C (4) was eventually formed via a macrolactamization to afford celogentin C (4) in 23 steps from simple α-amino acid building blocks.
