Title:
軸不斉ホスフィン化合物とその製造方法
Document Type and Number:
Japanese Patent JP5546294
Kind Code:
B2
Abstract:
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.) [Representative drawing] none
