Lactim Ethers in the Synthesis of 1,2-Polymethylene-4-quinazolones

Condensation of lactim ethers with amides of o-halogeno-substituted aromatic acids was investigated. Derivatives of 5,7,8,9,10,11-hexahydroazepino[1,2-a]quinazolin-5-one and 1,2,3,4-tetrahydropyrrolo-[1,2-a]quinazolin-5-one were obtained.
