Cannabisin A, an arylnaphthalene lignanamide from fruits of Cannabis sativa
摘要:
A new lignanamide, named cannabisin A, a known lignanamide, grossamide, and three known amides, N-trans-caffeoyltyramine, N-trans-feruloyltyramine, N-p-coumaroyltyramine, were isolated from the fruits of Cannabis sativa. The structure of cannabisin A has been established as 6,7-dihydroxy-1-(3,4-dihydroxyphenyl)-N1,N2-bis-[2-(4-hydroxyphenyl)ethyl]-2,3-naphthalenedicarboxamide, on the basis of chemical and spectral evidence.

contain a β⁻β' bond between the two phenylpropanoid units and to lack carbon number 9 from the parent lignan structure, are the most rarely occurring compounds within this class of natural compounds. We present here an overview of the structure, occurrence and biological activity of thirty-five 9-norlignans reported in the literature to date. In addition, we report the semisynthetic preparation of sixteen
