Article abstract of DOI:10.1007/BF01165731

The reaction of 1,3-dimethyl-5,6-diaminouracils with chalcones produced 7,9-dimethyl-2,4-diaryl-1,7,9-triazaspiro[4,5]decene-1-6,8,10-triols. The transformation of these spiro-compounds to pyrimido[4,5-d]oxazoles was investigated. 1997 Plenum Publishing Corporation.
