概要

• 論文の詳細を見る

• 2-Benzoxepines have efficiently been synthesized from Morita-Baylis-Hillman adducts, alkyl 3-aryl-3-hydroxy-2-methylenepropanoates by treatment with HCHO catalyzed by silica supported perchloric acid (HClO_4・SiO_2) or Amberlyst-15 in CH_2Cl_2 under reflux for a short period of time (1.5-2.5h). The catalyst can be recovered and recycled. The antibacterial properties of the new 2-benzoxepines were studied but no activity was found.
