[作者:ZHOU ZHONGHUA; FANG ZHUAN; JIN HUI; CHEN YUE; HE LING,期刊:Synthesis, 页码:3980-3986 , 文章类型: Article,,卷期:2010年-23]
- Quercetin was monomethylated under mild conditions in moderate yields through selective deprotection. The combined effects of the protecting group and the heating mode on the reactivity were investigated. The presence of...
- Diastereoselective Synthesis of trans-2,3-Dihydrothiophenes via Multicomponent Reactions of Pivaloylacetonitrile, Aldehyde, Amine, and Thiazolidinedione
[作者:SUN JING; WU QUN; XIA ERYAN; YAN CHAOGUO,期刊:Synthesis, 页码:3987-3992 , 文章类型: Article,,卷期:2010年-23]
- Polyfunctionalized trans-2,3-dihydrothiophenes are efficiently synthesized from the four-component reactions of thiazolidine-2,4-dione, aromatic aldehydes, secondary amines, and pivaloylacetonitrile. The reaction mechani...
- Adducts of Diketene, Alcohols, and Aldehydes: Useful Building Blocks for 3,4-Dihydropyrimidinones and 1,4-Dihydropyridines
[作者:ALIZADEH ABDOLALI; ROSTAMNIA SADEGH,期刊:Synthesis, 页码:4057-4060 , 文章类型: Article,,卷期:2010年-23]
- A novel, one-pot, solvent-free synthesis of 3,4-dihydropyrimidin-2-(1H)-one and 1,4-dihydropyridines derivatives via a four-component cyclocondensation reaction of diketene, alcohol, and aldehyde with urea or ammonium ac...
