    • In principle, a 1,3-diaza-1,3-butadiene bearing at least one hydrogen at position-4 and a leaving group at position-1 should also lead to pyrimidines with activated acetylenes. 1,4-Bis(dimethylamino)-2-phenyl-1,3-butadiene was synthesized for this purpose and found to not undergo cycloaddition with DMAD under a wide variety of neutral and acidic (Brønsted, Lewis) conditions (R. Greenhouse. Unpublished observations).
