METHOD OF PRODUCING AMINOBUTENE DERIVATIVE

摘要

PROBLEM TO BE SOLVED: To provide a method of producing an aminobutene derivative that is represented by general formula (I-1), wherein R1 is H, a protecting group for hydroxyl, a substituted or unsubstituted aromatic hydrocarbon group or a substituted or unsubstituted heterocyclic group; R2 is H, an alkoxy group, a substituted or unsubstituted alkyl group, a substituted or unsubstituted aromatic hydrocarbon group or a substituted or unsubstituted heterocyclic group; R3 is a substituted or unsubstituted acyl group, an alkoxy-carbonyl group, sulfonyl group or a substituted alkyl group. SOLUTION: An aminobutene derivative represented by general formula (I-2), wherein R1 and R2 are both identical with the groups defined in the general formula (I-1) is deprotected to give the objective aminobutene derivative of the general formula (I-1).
