摘要:
An enantioselective synthesis of the Strychnos alkaloid (-)-tubifoline, involving the kinetic resolution of racemic 1-(3-pyridyl)ethanol, the orthoester Claisen rearrangement of the enantiopure allylic alcohol 5, Smith indolization of the resulting 4-piperidineacetate 6, photocyclization of chloroacetamide 9, and final transannular cyclization, is reported.
