- Synthesis, Characterization, and Reactivity of N-Acyl Chloroformamidines: Useful Building Blocks for the Construction of N-Acyl-Substituted 1,1-Diaminoethylenes, Amidines, Ureas, and Thioureas
[作者:WANG YANG; CHI YUE; ZHAO FEI; ZHANG WENXIONG; XI ZHENFENG,期刊:Synthesis, 页码:347-354 , 文章类型: Article,,卷期:2013年45-3]
- The systematic synthesis of a series of N-acyl chloroformamidines is achieved by reaction of carbodiimides with acid chlorides; the structure of an N-acyl chloroformamidine was confirmed by X-ray diffraction. The reactiv...
- Synthesis of Tricyclic Lactams from Heterocyclic Imines
[作者:STALLING TIMO; MARTENS JUERGEN,期刊:Synthesis, 页码:355-364 , 文章类型: Article,,卷期:2013年45-3]
- Starting from different heterocyclic imines, a large number of annulated tricyclic lactams were prepared in a two-step synthesis. First, methoxyamides with a phenyl ring in alpha- or beta-position were generated. Finally...
- Efficient Synthesis of 5H-Indazolo[3,2-b]-1,3,4-benzotriazepines by a Tandem Aza-Wittig Cyclization
[作者:ZHAO FENFEN; ZHANG HAO; DING MINGWU,期刊:Synthesis, 页码:365-369 , 文章类型: Article,,卷期:2013年45-3]
- 5H-Indazolo[3,2-b]-1,3,4-benzotriazepines were directly prepared by the reaction of azides with triphenylphosphine via a tandem aza-Wittig cyclization in good yields.
- Formal Synthesis of (-)-Oseltamivir Phosphate
[作者:TRAJKOVIC MILOS; FERJANCIC ZORANA; SAICIC RADOMIR N,期刊:Synthesis, 页码:389-395 , 文章类型: Article,,卷期:2013年45-3]
- The formal synthesis of (-)-oseltamivir phosphate (Tamiflu (TM)) was accomplished starting from (S)-pyroglutamic acid. The synthesis comprised two carbon-carbon bond forming reactions, the first one being a diastereosele...
- An Efficient One-Pot Synthesis of 3,5-Diaryl-4-bromopyrazoles by 1,3-Dipolar Cycloaddition of In Situ Generated Diazo Compounds and 1-Bromoalk-1-ynes
[作者:SHA QIANG; WEI YUNYANG,期刊:Synthesis, 页码:413-420 , 文章类型: Article,,卷期:2013年45-3]
- A simple, highly efficient, one-pot synthesis of 3,5-diaryl-4-bromopyrazoles via 1,3-dipolar cycloaddition of diazo compounds and alkynyl bromides has been developed. The diazo compounds and alkynyl bromides were generat...
