Abstract

The asymmetric synthesis of (-)-swainsonine and (-)-8-epi-swainsonine is reported through the addition of either the allenylzinc or the allenyl lithio cyanocuprate reagents derived from [3-(methoxymethoxy)prop-1-ynyl]trimethylsilane to enantiopure α,β-dialkoxy N-tert-butanesulfinylimines derived from d-erythronolactone.

Abstract

A highly stereoselective approach for the synthesis of trans-1,2-disubstituted cyclobutanes through an Al-promoted cobalt-mediated O-->C ring contraction of dihydropyrans is described. [reaction: see text].
