Title:
METHOD FOR PRODUCING ACYLOXAZOLONE DERIVATIVE AND β-KETOAMINO ACID DERIVATIVE
Document Type and Number:
Japanese Patent JP2007031428
Kind Code:
A
Abstract:
To provide an industrial production method of an acyloxazolone compound in which the acyloxazolone compound capable of converting to a β-ketoamino acid derivative can be produced in short steps, good efficiency and high yield under inexpensive conditions not requiring a strong base, an expensive reagent and very low temperature and aftertreatment/refining can be produced by a ready method.
The present invention provides the method for producing the acyloxazolone compound in which the acyloxazolone compound is obtained by reacting an oxazole compound with an acylating agent such as an acid halide or an acid anhydride in the presence of a Lowis acid and a method for producing the β-ketoamino acid derivative from the acyloxazolone compound.
