Axially asymmetric phosphorus compound and production method thereof

摘要

To provide an axially asymmetric optically active biarylphosphorus compound that can easily produced without the step of optical resolution which was almost indispensable in conventional methods. [Means for solving the problems] A method for producing an axially asymmetric phosphorus compound represented by the general formula (1) , comprising a cycloaddition reaction of a compound having a triple bond with the use of a catalyst containing rhodium metal and an optically active bisphosphine. (In the formula (1) , R 1 and R 2 may be the same or different and independently are an alkyl group optionally having a substituent group, a cycloalkyl group optionally having a substituent group, an aryl group optionally having a substituent group, an alkoxy group optionally having a substituent group or an aryloxy group optionally having a substituent group; * is axial asymmetry.)
