  Synthesis of 2-Benzylidene and 2-Hetarylmethyl Derivatives of 2H-1,4-Benzoxazin-3-(4H)-ones as Neuroprotecting Agents

  摘要：

  A wide variety of the title compounds were synthesized by conventional and microwave methods in which the main step is a condensation of an aldehyde with a 1,4-benzoxazin-3-(4H)-one. In all cases, the Z diasteromers were the major products. Of particular importance is the synthesis of novel 2-(3,5-dibromo-4-hydroxy) and 2-(4-acetoxy-3,5-dibromobenzylidene derivatives of 2H-1,4-benzoxazin-3-(4H)-ones, four of which were shown in a previous publication to exhibit potent neuroprotecting properties. The yields of titled compounds ranged from 25 to 83%.
