Multi-membered N-heterocycles R 0690Lactim Ethers in the Synthesis of 1,2-Polymethylene-4-quinazolones. -The condensation of lactim ethers (I) with amides of o-halogeno-substituted aromatic acids (II) to quinazolin-5-one derivatives (III) is investigated. The success of the reaction depends on the size of the lactim ether ring, as well as on the nature of substituents on the benzamides. -(NAZARENKO, K. G.; SHYROKAYA, T. I.; TOLMACHEV*, A. A.; Synth.
