Dual ortho interaction in 2-substituted-3-(2-methylphenyl)-4(3H)-quinazolinones and their thio analogues under electron impact conditions

Competing ortho interactions, involving the CX and the ortho‐methyl substituent on the 3‐phenyl moiety, resulting in the eliminations of ˙CH3 and ˙OH/˙SH from the molecular ions of 2‐substituted‐3‐(2‐methylphenyl)‐4(3H)‐quinazolinones and their thio analogues, were observed. An intramolecular aroma...
