Development of a Stepwise [3 + 3] Annelation to Functionalized Piperidines
摘要:
A stepwise formal [3 + 3] cycloaddition sequence via a Grignard addition-cyclization reaction leads to a much improved piperidine synthesis. This methodology provides improved flexibility in both the aziridine substrate and TMM equivalent.

A stepwise [3+3] annelation sequence is described that generates tetrahydropyridines from the corresponding aziridines. The scope of this process is described and its potential for the stereoselective synthesis of indolizidines is highlighted by the synthesis of (-)-monomorine. (C) 2008 Elsevier Ltd.
