Abstract One-pot, three-component condensation reaction between (phenylsulfonyl)acetonitrile, aromatic aldehydes, and α-naphthol for preparation of 4-(aryl)-3-(phenylsulfonyl)-4H-benzo[h]chromen-2-amine derivatives has been reported. The method involves domino Knoevenagel condensation/Michaeladdition, and cyclization cascade. The reaction was performed in glycerol, which is a commercially available

A concise and efficientapproach to the synthesis of structurally diverse 6,8a-dihydropyrido[2,3-d]pyrimidine derivatives has been accomplished by a three-component reaction involving sulfonyl acetonitrile, an aromatic aldehyde, and 6-aminouracil. The method involves the domino Knoevenagel condensation/Michael addition/cyclization cascade in the presence of triethylamine in refluxing ethanol.

Abstract A new and green method for the synthesis of α,β-unsaturated arylsulfones had been achieved through the condensation of aromatic aldehydes, chloroacetonitrile, benzenesulfinic acidsodiumsalt in the presence of 1-butyl-3-methyl imidazolium hydroxide ([bmim]OH) in EtOH under reflux. The ionic liquid was recovered and recycled for subsequent reactions. The advantages of this protocol were non-toxic
