In this article, a one-pot protocol was established for the synthesis of bicyclic pyrrole ketone compounds. This method based on the building blocks of heterocyclic ketene aminals 1, which reacted with oxalaldehyde 2 in 1,4-dioxane at 50℃ and triethylamine as base. As a result, a series of bicyclic pyrrole ketone compounds 3a~3i have been synthesized. This reaction has some advantages such as simple synthetic route, readily available starting materials, high yields and simple work-up procedures.

Key words: bicyclic pyrrole ketone, heterocyclic ketene aminals, oxalaldehyde
