core of the final products was obtained by a late-stage anodic treatment. (R)-Naphthotectone was obtained in six steps from leuconaphthazarin with an overall yield of 38 % and an enantiomeric excess of 86 %. This compound was found to have the same absolute configuration as the natural product at its C-3′ stereogenic center. (S)-Naphthotectone was obtained in five steps from leuconaphthazarin with an

Sonogashira coupling of 7-iodobenzotriazole derivative 9 with propargylic alcohols followed by alkyne reduction leads to alkanols 11 or alkanols 12 which cyclize upon benzyne generation to give the iodo-chromanes 14 and iodo-chromenes 16. (C) 1998 Elsevier Science Ltd. All rights reserved.
