A METHOD FOR MANUFACTURING A ß-DIARYL ELECTRON WITHDRAWING GROUP SUBSTITUTED COMPOUND

摘要

Disclosed is a method for producing a .beta.-diaryl electron-withdrawing group substituted compound at high yield with high selectivity. Specifically , an optically active .beta.-diaryl electron-withdrawing group substituted c ompound represented by the general formula (V) below is produced by reacting an electron-withdrawing group substituted-.beta.-arylolefin derivative repr esented by the general formula (I) below with an arylboron represented by th e following general formula (II): Ar2-BXmMn in the presence of a compound re presented by the following general formula (IV): RhYoL1 p(Chiraphos)q (where in Y represents ClO4, BF4, PF6, SbF6, OTf, a halogen atom, a hydroxy group, an alkoxy group or an acyloxy group, and L1 represents an organic ligand). [ chemical formula 1] (I) (In the formula, Ar1 represents an aryl group, and E represents a formyl group, an acyl group or the like.) [chemical formula 3] (V)
