  • Method for making acylamides by synthesizing and acylating benzoxazines

    公开号:US20040044206A1
    公开(公告)日:2004-03-04
    A method is provided for synthesizing acylamides, useful as protectant for cultivated plants. A benzoxazine, such as 3,4-dihydro-3-methyl-2H-1,4-benzoxazine, is made in a stepwise manner by initially forming an o-nitrophenoxyketone by reacting a haloketone and a nitrophenol. The o-nitrophenoxyketone is hydrogenated to form the corresponding benzoxazine, which is thereafter acylated with an acylhalide to produce the acylamide, such as 4-dichloroacetyl-3,4-dichloroacetyl-3,4-dihydro-3-methyl-2H-1,4-benzoxazine.
