Abstract

(11aS)- and (11aR)-2,3-dimethoxy-naphtho[1,2-b]indolizidine (9a and 9b) were synthesized from optically pure L- and D-glutamic acid through several steps (scheme 1). All the intermediates of the route to the optical antipodes of 9 exhibit identical physical and spectral properties except the sign of the optical rotation values. The optical purity of the enantiomers of 6 was checked by 1H-NMR ...
