Abstract:
To provide an axially asymmetric optically active biaryl ester compound that can easily produced without the step of optical resolution which was almost indispensable in conventional methods. There is provided a method for producing an axially asymmetric ester compound, comprising a cycloaddition of a compound having a triple bond with the use of a catalyst containing rhodium metal and an optically active bisphosphine.
