Ismail, I. Imam published the artcileReactions with coumarin. VI, Application In Synthesis of 10543-42-7, the publication is Afinidad (2002), 59(498), 151-154, database is CAplus.
The present investigation is designed to study the reaction of some active methylene compounds with coumarin-6-sulfonyl hydrazones, I (X = O, S). The following active methylene compounds were used: malononitrile, Et cyanoacetate, di-Et malonate and 2,4-pentanedione. It was found that, the active methylene compound is added to the double bond of the hydrazone to give an adduct, which cyclized directly to pyrazole or pyrazoline-5-one derivatives, e.g. II.
