THE STEREOSPECIFIC SYNTHESIS OF (-)-(8R) AND (-)-(8S)-METHYLCANADINE

Autor: Stephen G. Davies, Julian Blagga, K. H. Sutton, Peter D. Baird

Publikováno v: TETRAHEDRON. 44(1)

Regioselective complexation of the dimethoxy arene ring of canadine to the Cr(CO)2 moiety gives two diastereoisomers which are separated by flash chromatography. Deprotonatlon of either diastereoisomer with n -butyllithium followed by addition of met
