Abstract

AbstractCarbodiimides react under very mild conditions with 2‐(bromomethyl)acrylic acid at both N atoms to give 1,3‐disubstituted‐5‐methylene‐6H‐pyrimidine 2,4‐dione derivatives in moderate to good yields. These products behaved as good Michael acceptors towards a variety of nucleophiles such as bromine, hydrochloric acid, hydrides, etc. A plausible mechanism is proposed based on theoretical approaches and experimental results.
