N-Phenylpyrrole and pyrazole nitriles 3,4,10 were prepared in one step from the corresponding aldehydes. The nitriles were converted into novel amidines 5,6,14 and related diamines 7,8,12 were also prepared from the aldehydes. The orientation of the phenyl ring to the basic function was controlled by modifying the torsional angle between the rings by methyl group substitution on the heterocycle.
由相应的醛一步制备N-苯基吡咯和吡唑腈3,4,10。将腈转化为新颖的am 5、6、14,并从醛中制备相关的二胺7、8、12。苯环相对于基本功能的取向是通过通过杂环上的甲基取代来改变环之间的扭转角来控制的。
