5,6-Dihydro-1,3-dimethyl-6-methylene-5-[(substituted amino)methylene]-2,4(1<I>H</I>,3<I>H</I>)-pyrimidinedione intermediates (<B>E</B>) were characterized spectroscopically and chemically. The cycloaddition reaction of <B>E</B> with olefinic dienophiles was carried out in highly regio- and stereoselective manners to give quinazoline derivatives.
