1A novel and efficient synthesis of pyrazolo[3,4-d]pyrimidine derivatives and the study of their anti-bacterial activity显示文摘In this work 4-amino-6-aryl-2-phenyl pyrimidine-5-carbonitrile derivatives were synthesized through a one-pot,three-component reaction of an aldehyde,malononitrile and benzamidine hydrochloride,in the presence of magnetic nano Fe_3O_4 particles as a catalyst under solvent-free conditions.3-Amino-6-aryl- 2-phenylpyrazolo[3,4-d]pyrimidine derivatives were prepared through an efficient and environmentally friendly reaction between 4-amino-6-aryl-2-phenylpyrimidine-5-carbonitrile derivatives and hydrazine hydrate and their antibacterial activity has been evaluated.Shahnaz Rostamizadeh Masoomeh Nojavan Reza Aryan Hamid Sadeghian Mahdieh Davoodnejad 2013Chinese Chemical Letters2013,24,7:7
2Synthesis of N^2-arylaminopyrimidine-5-carbonitrile derivatives via S_NAr amination reaction显示文摘An efficient and high-yielding synthesis of N^2-arylaminopyrimidine-5-carbonitrile derivatives starting from arylamines and 2-methylthio-pyrimidine-5-carbonitriIe derivatives has been developed in the presence of cesium carbonate as basic reagent.This new protocol showed high chemical tolerance for a range of functional groups,and only the methylthio substituent on C2 of the pyrimidine ring was replaced with arylamine derivatives under the reaction conditions.Shahnaz Rostamizadeh Masoomeh Nojavan Reza Aryan 2015Chinese Chemical Letters2015,26,1:1
3Zinc chloride catalyzed synthesis of 5-substituted 1H-tetrazoles under solvent free condition显示文摘锌氯化物是有效、安全的催化剂在[3 + 2 ] 器官的卵的出租机动三轮车增加反应少些在溶剂与钠叠氮化物激怒状况。相应 5 代用品 1H tetrazoles 在温和条件下面被获得。这个方法能克服劣势例如:有毒的金属和昂贵的试剂,激烈的反应条件,水敏感和危险水螅的存在的使用动物的酸。Shahnaz Rostamizadeh Hamid Ghaieni Reza Aryan Ali Amani 2009Chinese Chemical Letters2009,20,11:0
