Abstract
A one-pot stereoselective alkenylation of 1-(3-chlorophenyl)-3-methyl-1,4-dihydro-5-pyrazolone 2 by 2H-pyran-2-ones 1 to give (E,E)-5-aryl-5-[1-(3-chlorophenyl)-3-methyl-5-oxo-1,5-dihydropyrazol-4- ylidene]-3-methylsulfanyl-pent-3-en-carbonitrile/methyl carboxylate 3 has been delineated through ring transformation in moderate yields.
