This application relates to a method for preparing carbamate compounds from dioxazolone derivatives, comprising the following steps: reacting a dioxazolone derivative with a hydroxyl-containing compound in the presence of a catalyst to prepare the carbamate compound. The catalyst includes one or more of dichlorobis(4-methylisopropylphenyl)ruthenium(II), tri(acetylacetonate)ruthenium(III), cyclooctadiene ruthenium(II) chloride, and dichloro(pentamethylcyclopentadienyl)iridium(III) dimers. This synthetic method is universally applicable to the synthesis of carbamate compounds with different group types (such as alkyl, aryl, heteroaryl, etc.), and exhibits high yields and mild reaction conditions.
