• 論文の詳細を見る

• The reaction of haloketenes with 1,3-diaza-1,3-diene compounds, prepared by condensation of 2-amino-heterocycles with aromatic aldehydes, gave the [2+4] cycloadducts, fused pyrimidinones (6-17). However, haloketenes underwent the cycloaddition with 2-(p-anisylideneamino)-benzimidazole (5) to give both pyrimido [1,2-a] benzimidazoles (18 and 19) and 2-azetidinones (20-22).
