Stereocontrolled preparation of bicyclic alkaloid analogues: an approach towards the kinabalurine skeleton
摘要:
An approach towards the construction of bicyclic analogues of monoterpene alkaloids belonging to the kinabalurine, incarvilline and skytanthine families Of natural products is reported These syntheses rely oil a stereoselective intramolecular Pauson-Khand cyclisation of a chiral pool-derived enyne in order to prepare the bicyclic core Stereoselective further elaboration generates diastereomeric analogues of the naturally occurring alkaloids (C) 2009 Elsevier Ltd All rights reserved
