METHOD OF PRODUCING ALKYLOXYAMINOFURANONE DERIVATIVE

摘要

PROBLEM TO BE SOLVED: To provide a method of inexpensively and simply producing an alkyloxyaminofaranone derivative in a practically industrial scale. SOLUTION: The objective industrial method for producing an alkyloxyaminofuranon derivative starts with the reduction step of a compound represented by general formula (A) followed by the step of cyclization of the reduced product to a compound represented by general formula (D) [wherein R1 and R3 are each same defined as in the general formula (A)].
