  • Abstract
    A facile and efficient one-pot synthesis of 3-[bis(alkyl­thio/alkylamino)methylene]-5-(pyridyl/quinoylmethyl) furan-2,4 (3H,5H)-diones 3 and 10, based on a sequential aldol condensation and lactonization reaction between (alpha)-oxo ketene-S,Sacetals 1 and pyridine/qinoline-carboxaldehydes 2 in aqueous media, has been developed. A mechanism involving an acidcatalyzed intramolecular oxa-pyridylethylation reaction is proposed for the ­formation of the lactone ring.
