Abstract
β-Dicarbonyl compounds, such as diethyl malonate, ethyl acetoacetate and acetyl acetone have been found to add selectively to the iminoether functionality of the 2-ethoxymethyleneaminonitriles leading to a one-pot synthesis of some quinazoline and fused pyrimidine derivatives.
Key words
annulations - heterocycles - nitriles - Lewis acids - tin
