—— | 4-acetoxy-1,7-diacetyl-6,7-dihydropyrrolo<2,3-c>azepin-8(1H)-one | 96562-98-0 | C14H14N2O5 | 290.276 |
Aromatic aldehydes , but not ketones, can be condensed with glycocyamidine . The corresponding alkylbenzylideneglycocyamidines may be made from glycidic esters by reaction with guanidine, followed by cyclization with acetic anhydride. A number of mono- and di -acetylated derivatives of 6,7-dihydropyrrolo[2,3-c]azepine-4,8(1H,5H)- dione have been prepared, but failed to undergo the Darzens reaction. Bromo- and iodo-2-arylazoimidazoles, protected on nitrogen by the methoxyethoxymethyl group, failed to undergo clean lithiation.
