Synthesis of 5-Aryl-3(2 H)-furanones Using Intramolecular Cyclization of Sulfonium Salts

Base-induced intramolecular cyclization of novel (4-aryl-2,4-dioxobutyl)methylphenylsulfonium salts prepared from the commercially available 1-arylethanone by a cost-effective process is described in this paper. The reaction was completed within 10 min to produce a family of 2-unsubstituted 5-aryl-3(2H)-furanones in excellent yield. This procedure is simple, and can be carried out under mild conditions and an ambient atmosphere.

Efficient and regioselective one-step synthesis of 7-aryl-5-methyl- and 5-aryl-7-methyl-2-amino-[1,2,4]triazolo[1,5-a] pyrimidine derivatives

Two facile and efficient one-step procedures for the regioselective synthesis of 7-aryl-5-methyl- and 5-aryl-7-methyl-2-amino-[1,2,4]triazolo[1,5-a]pyrimidines have been developed, via reactions of 3,5-diamino-1,2,4-triazole with variously substituted 1-a

Substitution of acyl for acetyl with N-acylbenzotriazoles catalyzed by samarium triiodide

Catalyzed by samarium triiodide (SmI3), substitution of acyl with N-acylbenzotriazoles for acetyl in acetoacetic esters and acetylacetone proceeds smoothly under neutral conditions in open air, affording the corresponding β-keto esters and β-diketones in good yields.

Group transfer reactions using benzimidazolides

Transfer of aroyl group from N-aroylbenzimidazoles 1a-d to the enolates generated from ethyl acetoacetate 2 and acetylacetone 3 has been achieved successfully. in-situ Cleavage of acetyl group of the acetylated products has also been observed.
