  Synthesis of 6,6′-Binaphthopyran-2-one Natural Products: Pigmentosin A, Talaroderxines A and B

  摘要：

  Efficient and stereoselective syntheses of pigmentosin A, talaroderxine A, and its diastereomer talaroderxine B are reported. The binaphthyl ring system is assembled by vanadium-catalyzed phenolic coupling of tricyclic precursors. These key intermediates were prepared by Michael-Dieckmann annulation of a protected orsellinate ester, with the requisite pyranones accessed by a new variant of Ghosez's sulfone-epoxide annulation. Preliminary biological experiments are reported for pigmentosin.

  Various naphthopyranones were synthesized and tested for their cytotoxicity and apoptotic activity. The synthesis was carried out using two building blocks, which were prepared from enantiomerically pure oxiranes and methyl acetoacetate and then reacted with each other to form naphthopyranones. Monomeric and dimeric naphthopyranones were synthesized and then a structure–activity relationship study
