3-(N-ACYLAMINO)-3-(4-TETRAHYDROPYRANYL)-2-OXOPROPENOATE, AND METHOD FOR PRODUCING 3-(N-ACYLAMINO)-3-(4-TETRAHYDROPYRANYL)-2-OXOPROPANOHYDRAZIDE

摘要

PROBLEM TO BE SOLVED: To provide a method for industrially preferably producing a 3-(N-acylamino)-3-(4-tetrahydropyranyl)-2-oxopropanohydrazide. SOLUTION: This method for producing 3-(N-acylamino)-3-(4-tetrahydropyranyl)-2-oxopropanohydrazide comprises reacting a 2-acyloxy-3-(4-tetrahydropyranyl)-3-oxopropanoate with an aminating agent to produce a 2-acyloxy-3-(4-tetrahydropyranyl)-3-amino-2-propenoate of the formula (2) (R is a hydrocarbon group; R1is H or a hydrocarbon group), and then producing the 3-(N-acylamino)-3-(4-tetrahydropyranyl)-2-oxopropanohydrazide.
