A new flavanone-chromone biflavonoid, preussianone (1), has been isolated from the leaves of Garcinia preussii, along with four known biflavonoids. The absolute stereostructures were elucidated by chemical, spectroscopic, and chiroptical methods. The

The first preparation of the N,C-coupled naphthylisoquinoline alkaloid ancistrocladinium A and its likewise naturally occurring minor atropisomer, in an atropisomerically pure form, is described. The synthesis succeeded by resolution of the already r

The first regio- and stereoselective total synthesis of the axially chiral 7,3′-coupled naphthylisoquinoline alkaloids ancistrocladidine (1) and ancistrotectorine (2) has been described. Both possess a 7,3′-coupled axis, which before now, was dif

The first N,8'-coupled naphthylisoquinoline alkaloids with free phenolic OH groups, 4'-O-demethylancistrocladinium A and 6,4'-O-didemethylancistrocladinium A, have been isolated from the leaves and bark of the Vietnamese liana Ancistrocladus cochinch
