DOI: 10.1055/sos-SD-016-00745

Kikelj, D.Science of Synthesis, (200416673.

Sometimes, aromatization of 1,2-dihydro-, 3,4-dihydro-, and 1,2,3,4-tetrahydroquinazolines, e.g. 2-substituted 1,2-dihydroquinazolin-4(3H)-ones,[‌350‌,‌488‌,‌682‌,‌683‌,‌685‌] 4-substituted ethyl 3,4-dihydroquinazoline-3-carboxylates,[‌686‌] and 1,2,3,4-tetrahydroquinazolines,[‌687‌] can be accomplished by removal of carbofunctional groups. Some selected examples, illustrating different experimental conditions, are collected in Table 6.
