diexo-3-Aza-4-oxotricyclo[4.2.1.02,5]non-7-ene (1) reacted with carboximidic esters by ring expansion to yield tricyclic 5,6-dihydropyrimidin-4(3H)-ones 3; when the latter were refluxed in chlorobenzene solution, cyclopentadiene split off to give 2-alkyl, 2-aralkyl-, 2-cycloalkyl and 2-arylpyrimidin-4(3H)-ones 4a-h. This method, which is conveniently carried out in a "one-pot" reaction from 1, provides a good alternative pathway for the preparation of compounds 4.
