| Abstract: | Quinazolinones, I: Preparation, Crystal Structure, and Activity of 2-Methyl-3-(4-oxo-3-phenylthiazolidine-2-ylidenamino)-4(3H)-quinazolinone The cyclisation of 1-(3,4-dihydro-2-methyl-4-oxo-3H-quinazoline-3-yl)-3-phenylthiourea (2) with chloroacetic acid leads to 2-methyl-3-(4-oxo-3-phenyl-thiazolidine-2-ylidenamino)-4(3H)-quinazolinone (3) and not to the isomer 4 . The crystal structure of 3 has been determined and refined until R = 0.0715. Compound 3 possesses good hypnotic and anticonvulsant activities. |
