چکیده انگلیسی
Four new BINOL-based thiazole (thiadiazole) thioether ligands (S)-1, (S)-2, (S,S)-3 and (S)-4 were prepared. When their catalytic effectiveness was tested, good results (up to 93% ee and 97% yield) were obtained in the asymmetric addition of diethylzinc to aldehydes while poor results were obtained in the asymmetric conjugate addition of diethylzinc to enones.
Four new BINOL-based thiazole (thiadiazole) thioether ligands were prepared and their asymmetric catalytic effectiveness was tested.Figure optionsDownload as PowerPoint slide
