Abstract

Ten 2,5-dioxo- and 4-aryl-5-oxo-2-thioxo-1,2,3,4,5,6,7,8-octahydroquinazolines have been synthesized in three-component interactions of 1,3-cyclohexanedione or dimedone, urea or thiourea, and substituted benzaldehydes (3-bromo-, 4-bromo-, 4-fluoro-, 4-methoxy-, 3,4-methylenedioxy-, and 3-nitro-). 9-Aryl-4,5-dioxo-1,2,3,4,5,6,7,8-octahydro-9H-xanthenes were also formed in these reactions.
