Abstract
Synthesis and separation of cis- and trans-1,2,4,5,5a,6,7,8,9,9a-decahydrobenz[h]imidazo[1,2-c]quinazolines and its precursors are described. Inhibitory activity against collagen-induced platelet aggregation for rabbit blood of these compounds and their benzologues at A ring is also evaluated.
