The enantioselective building of butenolide is conducted via Krische's catalytic asymmetric allylation protocol. Following the radical translocation-cyclization effect, a hydroxymethyl team in the C-13 position was stereoselectively introduced by a one-pot partial reduction-allylation protocol for the unprotected lactam by-product. Finally, the sum total synthesis is completed by development of a C band.We report a chelation-assisted C-H arylation of numerous indoles with sterically and electronically diver
