    Project supported by the National Nature Science Foundation of China (Nos. 21362034, 21462038) and the Research Fund for the Doctoral Program of Higher Education of China (No. 20136203120005).

The S-allylic alkylation of 2-thiopyrimidine with Morita-Baylis-Hillman (MBH) carbonates catalyzed by 1,4-diazabicyclo[2.2.2]octane (DABCO) has been developed. A variety of Morita-Baylis-Hillman (MBH) carbonates reacted with 2-thiopyrimidine and gave the desired S-allylic alkylated products in 55%~99% yields with exclusive chemoselectivity and excellent regioselectivity. The mild reaction conditions, short reaction time, and broad substrate scope make this method very practical.

Key words: S-allylic alkylation, 2-thiopyrimidine, Morita-Baylis-Hillman (MBH) carbonates, allylic compounds, chemoselectivity, regioselectivity, heterocycles
