- Abstract
We have studied the reaction of o-aminophenyldiphenylcarbinol with substituted cyanothienopyridine, cyanopyridines, cyanopyridones, and cyanopyridinethiones. We have shown that in the case of pyridine derivatives, the reaction occurs with formation of 3,4-dihydroquinazolines, which exist in solution in two tautomeric forms. We have determined the general characteristics of initial fragmentation of the indicated products under electron impact.
