SYNTHESIS AND PROPERTIES OF DERIVATIVES OF CYCLOPENTAPYRAN AND CYCLOPENTATHIAPYRAN ISOELECTRONIC WITH AZULENE

Cyclopentapyran and cyclopentathiapyran derivatives isoelectronic with azulene have been synthesized by intramolecular cyclization of substituted octadienyne-dials.The cyclization reaction of octadienyne-dials proceeds regiospecifically and the formation of cyclopentapyrans and/or cyclopentathiapyrans depends on a subtle variety of the reaction conditions.
