2-Quinazolinones and their cyclic homologs (review)

Methods for the synthesis of 2-quinazolinones, 1,2-dihydro-3H-1,4-benzodiazepin-2-ones, 1,2,3,4-tetrahydro-1,5-benzodiazocin-2-ones, and 1,2,3,4-tetrahydro-5H-1,6-benzodiazonin-2-ones are examined along with the peculiarities of their structure, their tautomerism, their chemical properties, and their biological activity.Translated from Khimiya Geterotsiklicheskikh Soedinenii, No. 6, pp. 723–738, June, 1979.
