Abstract
The stereoselective total synthesis of the piperidine alkaloids, (+)-coniine, (+)-pseudoconhydrine and (+)-sedamine has been achieved through a common intermediate generated from butane-1,4-diol. The synthetic sequence involves a Maruoka asymmetric allylation and ring-closing metathesis as the key steps. (C) 2011 Elsevier Ltd. All rights reserved.
