This method develops pyrrol-2-one derivatives from furan-2-ones and ammonia, indicating a new synthesis pathway.
A method for the synthesis of pyrrol-2-one derivatives containing a yidenemalononitrile fragment in their structure has been developed. Their preparation is based on the initial interaction of furan-2-ones with ammonia, leading to the formation of γ-oxobutanamide intermediates. These compounds subsequently react with tetracyanoethylene, transforming into the target pyrrole derivatives.
