                                Synthesis of ?,?-disubstituted aldehydes involving metallated 1-aza-1,3-butadienes in the presence of phosphine complexes of palladium
                             
                            
                                摘要:
                                A novel catalytic method was developed for the synthesis of alpha,beta-disubstituted aldehydes by the reaction of N-, O-, and S-containing allyl electrophiles with magnesium azaenolates obtained by metallation of alpha,beta-unsaturated imines by Grignard reagents. The reaction is carried out with high regio- and stereo-selectivity in the presence of phosphine complexes of palladium.
