Abstract
It is shown with 1-ethoxyisoindolenine that the reaction of lactim ethers with α-amino-α-cyanoacetamide also extends to partly aromatized lactim ethers, although these react much less readily. Condensation of 1-ethoxyisoindolenine with α-amino-cyanoacetamide gives 4-carbamido-5-aminoimidazo[1, 2-1′, 2′]isoindoline, from which a new series of purinoisoindioline derivatives is synthesized.
