Wang, Tao; Chen, Xuling; Li, Pengfei published the artcile< One-Pot Divergent Synthesis of Benzoxazines and Dihydroquinolines from Morita-Baylis-Hillman Alcohols>, Quality Control of 20776-50-5, the main research area is hydroxy carboxypropylene benzamide intramol heterocyclization; carboxyethylene benzoxazine preparation; acyl dihydroquinoline carboxylate preparation.
Benzoxazines and hydroquinolines was prepared by a one-pot process via catalyst-controlled divergent annulations of Morita-Baylis-Hillman (MBH) alcs. In the presence of diazabicyclo[2.2.2]octane, MBH alcs. reacted with Boc2O to form MBH carbonates, followed by intramol. annulation to give 4H-benzo[d][1,3]oxazines. Divergently, the combination of Bu4NBr and NaOH enabled the formation of 1,2-dihydroquinolines from the same starting materials.
European Journal of Organic Chemistry published new progress about Alcohols Role: RCT (Reactant), RACT (Reactant or Reagent). 20776-50-5 belongs to class bromides-buliding-blocks, and the molecular formula is C7H6BrNO2, Quality Control of 20776-50-5.
