[作者:HASSAN ALAA A; IBRAHIM YUSRIA R; SHAWKY AHMED M,期刊:Journal of Heterocyclic Chemistry, 页码:118-124 , 文章类型: Article,,卷期:2010年47-1]
- Nucleophilic attack by substituted hydrazides on C-2, C-3 of 2,3,5,6-tetrachloro-14-benzoquinone and 2,3-dichloro-1,4-naphthoquinone initiates the formation of benzo[e][1,3,4]oxadiazine and benzo- as well as naphthoxadia...
- An Efficient Synthesis of Pyrido[2,3-d]pyrimidine Derivatives in Ionic Liquid
[作者:SHI DAQING; ZHOU YAO; LIU HAI,期刊:Journal of Heterocyclic Chemistry, 页码:131-135 , 文章类型: Article,,卷期:2010年47-1]
- A series of 5,7-diarylpyrido[2,3-d]pyrimidine-2,4(1H,3H)-diones was synthesized via the reaction of 6-aminopyrimidine-2,4-dione and alpha,beta-unsaturated ketones in ionic liquid without using any catalyst. This protocol...
- Synthesis and Herbicidal Activity of O,O-Dialkyl N-[2-(5,7-dimethyl-[1,2,4]triazolo[1,5-a]pyrimidin-2-yloxy)benzoxyl]-1-amino-1-substitutedbenzyl Phosphonates
[作者:TANG WU; SHI DEQING,期刊:Journal of Heterocyclic Chemistry, 页码:162-166 , 文章类型: Article,,卷期:2010年47-1]
- A series of novel 1,2,4-triazolo[1,5-a]pyrimidine derivatives containing an alpha-amino phosphonate moiety 5 were designed and synthesized by the multi-step reactions. Their structures were clearly confirmed by spectrosc...
