摘要:
PROBLEM TO BE SOLVED: To provide a method for producing a benzoxazine derivative represented by chemical formula 1 (wherein X 1 is a halogen atom). SOLUTION: The method for producing the benzoxazine derivative used as an antibacterial medicine comprises treating a starting raw material with an enzyme, etc., having an ester asymmetric hydrolysis ability or reacting the starting raw material with an optically active organic base to give a carboxylic acid compound represented by formula (III-1-a) or converting the raw material to an azomethin derivative and then carrying out asymmetric reduction of the azomethin derivative to give the compound represented by formula (III-1-a) and then reducing the compound represented by formula (III-1-a) to give the corresponding alcohol substance and cyclizing the alcohol substance in the presence of a base to afford a compound having a [1,4]benzoxazine ring, reacting the compound with a dicarboxylic acid ester such as ethoxymethylene malonic acid diethyl ester, then treating the reaction product with boron trifluoride compound to give a boron chelate compound, binding 4-methylpiperazine to the chelate compound and cleaving and removing the boron chelate.
