A synthetic approach to novel 2-(1-glycosyl-1,2,3-triazol-4-yl)-3-hydroxyquinolone conjugates has been developed. The methodology involves preparation of a suitable quinoline intermediate and its subsequent conjugation with various acylated glycosyl

In this work, we attempted to synthesize thioflavonols using rearrangement of phenacyl thiosalicylates prepared by two different approaches and subjected to cyclization under acidic conditions. Contrary to our expectations, the isolated products were

A general and efficient synthesis of 4-substituted-1H-pyrazole-3,5-diamines was developed to access derivatives with an aryl, heteroaryl, or styryl group, which are otherwise relatively difficult to prepare. The first step is based on the Suzuki-Miya
