Synthesis Of (-)-Swainsonine And (-)-8-Epi-Swainsonine By The Addition Of Allenylmetals To Chiral Alpha,Beta-Alkoxy Sulfinylimines
ORGANIC LETTERS(2011)
摘要
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 alpha,beta-dialkoxy N-tert-butanesulfinylimines derived from D-erythronolactone.
