The HPLC enantiomeric separation of the racemic cularinoid alkaloids N-p-methoxy-1,alpha-dihydroaristoyagonine (1) and 4',5'-demethoxy-1,alpha-dihydroaristoyagonine (2) was accomplished using five chiral stationary phases (CSPs), some of them polysaccharide-derived ones. The molecular size and conjugative effect strongly affect the different enantioselectivity of the compounds 1 and 2 on the various CSPs investigated. Single enantiomers of 1 were isolated by repeated injections on an analytical… CONTINUE READING
