摘      要：A novel alkaloid compound with efficacious antihypertension activity was synthesized from one of heptatrienyl derivatives which was obtainod from curcumol by GUO Yong-tian et al. The structural determination of crystalline intermediate is very important for the structural elucidation of final reductive product and for designing and synthesizing
