Two analogs of blestriarene C (4,4'-dimethoxy-1,1'-biphenanthrene-2,2',7,7'-tetraol) bearing no 7,7'-dihydroxy (3) and 4,4'-dimethoxy groups were prepared. Unlike blestriarene C (1), compounds and , as well as 1,1'-biphenanthrene-2,2'-diol (5), do no

Here, we report a synthesis of a differentially protected, open-chain C21-C40 fragment of azaspiracid-1, corresponding to the lower half EFGHI-ring domain. The synthesis features modular coupling of three advanced intermediates, aiming for diverted a

Here, we report a synthesis of the lower half C21−C40 fragment of the shellfish toxin, azaspiracid-1. The C28−C40 fragment was synthesized by a coupling between the C28−C35 epoxide and the C36−C40 dithioacetal anion, followed by the HI-ring s
