4-amino-6-aryl-2-phenylpyrimidine-5-carbonitriles have been prepared in one step procedure from the readily available 4-aryl-2-amino-3-cyano-5,6,7,8-tetrahydro-7,7-dimethyl-5-oxo-4H-benzopyrans. The mass spectroscopy study under EI conditions shows molecular peaks with high intensity corresponding to the loss of benzonitrile from the C2 position of the pyrimidine ring. Semiempirical (AMI and PM3) and ab initio
一种新的4-氨基-6-芳基-2-苯基嘧啶-5-腈是从容易获得的4-芳基-2-氨基-3-氰基-5,6,7,8-四氢-7一步制备的。 ,7-二甲基-5-氧代-4 H-苯并吡喃。在EI条件下进行的质谱研究表明,具有高强度的分子峰对应于从嘧啶环的C2位上苯甲腈的损失。半经验(AMI和PM3)和从头开始的HF / 6-31G *计算显示了三个环不在同一平面上时偏爱的扭曲几何形状。
