Applications of NHC-mediated O- to C-carboxyl transfer: synthesis of (±)-N-benzyl-coerulescine and (±)-horsfiline
摘要:
NHC-promoted O- to C-carboxyl transfer of 3-allyl indolyl phenyl carbonates generates 3-allyl-3-phenoxycarbonyl-oxindoles with good catalytic efficiency, which are readily converted into (+/-)-N-benzylcoerulescine and (+/-)-horsfiline. (C) 2010 Elsevier Ltd. All rights reserved.
