摘要
(Chemical Equation Presented) A useful transformation in enantioselective synthesis: (-)-Sparteine-assisted lithiation of the propargylic 1-thiocarbamate 1 (Cb = CONiPr2) forms the enantiomerically and diastereomerically pure lithium (-)-sparteine complex 2. Its solid-state structure and application in the asymmetric synthesis of highly enantioenriched 1-thioallenes 3 were investigated. © 2005 Wiley-VCH Verlag GmbH & Co. KGaA.
