Abstract: Abstract An efficient telescope method for the preparation of furan-2(5H)-one derivatives containing 4H-chromen-4-one fragment was developed. The suggested approach based on tandem multicomponent reaction of 3-(dimethylamino)-1-(2-hydroxyphenyl)prop-2-en-1-one, arylglyoxals and Meldrum’s acid. A distinctive feature of the… read more here.

Abstract: We report here a highly efficient green approach for the synthesis of imidazolidin-2-ylidene-indenedione, pyrimidine-2-ylidene-indenedione and indenoquinoxaline derivatives through the one-pot three-component reaction between ninhydrin, malononitrile and various diamines in water medium under catalyst-free conditions. High… read more here.
