Abstract
(Chemical Equation Presented) The one-pot synthesis of various functionalized thieno[2,3-b]thiopyran-4-ones from readily available β-keto ε-xanthyl phosphonates has been accomplished by combining a Horner - Wadsworth - Emmons olefination with a base-induced intramolecular domino cyclization/thio-Michael addition. The use of cyclic ketones in this transformation allowed a facile access to novel spiro-type thieno[2,3-b] thiopyran structures.
