(2Z,5Z)-1-Aryl-3-hydroxy-5-[3,3-dimethyl-3,4-dihydroisoquinolin-1(2H)-ylidene]pent-2-ene-1,4-diones reacted with o-phenylenediamine and hydrazine to give 3-[(Z)-2-aryl-2-oxoethylidene]-1,2,3,4-tetrahydroquinoxalin-2-ones and 1-(3-aryl-1H-pyrazol-5-yl)-2-[(Z)-3,3-dimethyl-3,4-dihydroisoquinolin-1(2H)-ylidene]ethanones, respectively. The crystalline and molecular structure of 2-(Z)-8,8-dimethyl-2,3,8,9-tetrahydro[1,4]dioxino[2,3-g]isoquinolin-6(7H)-ylidene}-1-(3-phenyl-1H-pyrazol-5-yl)ethanone was determined by X-ray analysis.
