  General Enantiospecific Route to Isochromanquinones. Synthesis of (-)-Nanaomycin D

  摘要：

  A general enantiospecific synthesis of isochromanquinones is presented. This entails an efficient synthesis of (3aS, 5S, 7aR)-7-bromo-3,3a,5,7a-tetrahydro-5-methyl-2H-furo[3,2-b]pyran-2-one (12) and ultimately the lithium agent 15 from commercially available L-rhamnose. Addition of 15 to the appropriate cyclobutenedione followed by thermolysis of the resulting cyclobutenone leads to the isochromanquinones 16a-c. In an analogous fashion the naturally occurring product, (-)-nanaomycin D, was synthesized. In addition, new methodology involving the ring expansion of iminocyclobutenones to aminophenols was discovered.

  The first, enantiospecific total syntheses of pyranonaphthoquinone antibiotics, nanaomycins D and A, and their enantiomers, kalafungin and 4-deoxykalafunginic acid are described by an “enantiodivergent” strategy from a common optically active intermediate, (1S,3RS,4S)-3,4-dihydro-5,9,10-trimethoxy-1-methyl-1H-naphtho[2,3-c]pyran-3,4-diol, which has been derived from L-rhamnose via condensation of
