On January 31, 2014, Majee, A.; Kundu, S. K.; Santra, S.; Hajra, A. published an article.Category: esters-buliding-blocks The title of the article was An improved procedure of Miyashita protocol for the preparation of ureidomethylene derivatives of 1,3-dicarbonyl compounds. And the article contained the following:
The synthesis of ureidomethylene derivatives I [R1 = CH3, OCH2CH3; R2 = CH3, OCH2CH3, OCH3, OC(CH3), etc.], through a three-component condensation of 1,3-dicarbonyl compounds, urea and trimethylorthoformate in presence of zinc triflate under solvent-free conditions, has been developed. Me substituted ureas also give the condensation product under similar reaction conditions. The experimental process involved the reaction of (Trimethoxymethyl)benzene(cas: 707-07-3).Category: esters-buliding-blocks
The Article related to ureidomethylene preparation, urea trimethyl orthoformate dicarbonyl condensation, Aliphatic Compounds: Ketones and Derivatives, Including Sulfur Analogs and other aspects.Category: esters-buliding-blocks
