[作者:EL KAIM LAURENT; GIZZI MARION; GRIMAUD LAURENCE,期刊:SYNLETT, 页码:1771-1774 , 文章类型: Article,,卷期:2010年-12]
- We present a two-step procedure for the synthesis of 1,2,4-triazole derivatives from a primary amide and a hydrazine via an oxidative process.
- Synthesis of 2,5,6-Trisubstituted Benzimidazoles by Heck and Subsequent 6 pi-Electrocyclization-Dehydrogenation Reactions of 2,4,5-Tribromo-N-methylimidazole and 2-Aryl-4,5-dibromo-N-methylimidazoles

- 2,5,6-Trisubstituted benzimidazoles were prepared by Heck reactions of 2,4,5-tribromo-N-methylimidazole and 2-aryl-4,5-dibromo-N-methyl-imidazoles and subsequent 6 pi-electrocyclization-dehydrogenation reactions.
- Tetrahydrofurans from Substituted Hex-5-yne-1,4-diols
[作者:SCHWEHM CAROLIN; WOHLAND MAX; MAIER MARTIN E,期刊:SYNLETT, 页码:1789-1792 , 文章类型: Article,,卷期:2010年-12]
- It was discovered that substituted hex-5-yne-1,4-diols like 16, 28, and 30 undergo a domino sequence of Meyer-Schuster rearrangement followed by Michael addition forming 2,5-disubstituted tetrahydrofurans in presence of ...
- A New Effective Synthesis of Arene Mono- and Disulfonyl Chlorides

- Arene mono- and disulfonyl chlorides have been easily synthesized starting from the corresponding anilines via aqueous oxidative chlorination of S-aryl O-ethyl dithiocarbonates intermediates, aryl methyl sulfides, or fro...
- Microwave Irradiation for Accelerating Synthesis of [1,2,4]Triazole[4,3-a]-pyrimidines Based on Isoflavones
[作者:ZHANG ZUNTING; XIE JUAN; ZHU MULIN; XUE DONG,期刊:SYNLETT, 页码:1825-1828 , 文章类型: Article,,卷期:2010年-12]
- Microwave irradiation was used to accelerate the cyclo-condensation of isoflavones and 3-amino-1,2,4-triazoles in the presence of sodium methoxide to produce 6,7-diphenyl[1,2,4]triazolo[4,3-a]pyrimidines in good to moder...
