Cai, Wei; Zhou, Yiming; He, Yanlin; Huang, You published the artcile< DABCO catalyzed [4+2] annulations of Morita-Baylis-Hillman carbonates with isocyanates>, COA of Formula: C7H9NO, the main research area is alkoxy oxopropenyl dihydroquinazoline carboxylate preparation; MBH carbonate preparation isocyanate DABCO catalyst chemoselective cycloaddition.
A highly concise method for 1,4-diazabicyclo[2.2.2]octane (DABCO) catalyzed [4+2] annulations of o-amino-acylation of aryl Morita-Baylis-Hillman (MBH) carbonates with isocyanates was developed. For the first time, MBH carbonates served as 1,4-dipoles, providing functionalized 3,4-dihydroquinazolinones in mild conditions with good to excellent yields. The d. functional theory calculations of the mechanism supports this hypothesis.
Chemical Communications (Cambridge, United Kingdom) published new progress about [4+2] Cycloaddition reaction (chemoselective). 5344-90-1 belongs to class alcohols-buliding-blocks, and the molecular formula is C7H9NO, COA of Formula: C7H9NO.
