<p>The present invention addresses the problem of providing an aldol reaction catalyst and a method for producing a stereoselective cyclicβ-hydroxy aldehyde compound using this catalyst. As a means for solving the above-mentioned problem, the present invention provides a biaryl-type aldol reaction catalyst which is represented by general formula (I). (In the formula, R1, R2, R3a, R4a, Ra and R are as defined in the description.)</p> |
