PROBLEM TO BE SOLVED: To provide a method by which an optically active nitrogen-containing 3-membered ring compound is commercially and efficiently produced. SOLUTION: The method for production is carried out as follows: A carbamic acid ester such as benzyl N-chloro-N-sodiocarbamate is reacted with an olefin such as 3-acryloyl-2-oxazolidinone in the presence of an optically active quaternary ammonium salt, to afford the optically active nitrogen-containing three-membered ring compound such as 3-(1'-carbonyloxybenzylaziridinyl)-2-oxazolidinone.
