THE SYNTHESIS OF SOLUBLE POLYMER-SUPPORTED CHIRAL BINOL LIGANDS AND ASYMMETRIC ADDITION REACTIONS
Soluble polymeric ehiral binaphthol(BINOL)ligands have been synthesized thmugh copolymerizafion of 3
3'-bis(hydroxymethyl)-2
2’-bis(methoxymethy leneoxy)-1
1’-binaphthyl
1
6-dihydmxyhexane and 1
4-benzene diearbonyl chloride followed by deprotection of methoxymetbyleneoxy groups by‘PrOH/HCI
and their application in the enantioselective addition of dietbylzinc to benzaldehyde was investigated.All soluble polymeric chiral BINOL ligands were characterized by IR、1H—NMR、GPC and elemental analysis.which clearly demonstrated the formation of polymeric ehiral BINOL ligands.These soluble polymeric chiral ligands were found to be effective in the addition of diethylzinc to benzaldehyde either in the presence or in the absence of i(OiPr)4 with higher catalytic activities and lower enantioseleetivities.In the latter case
the dendritic chiral BINOL ligands showed much higher catalytic activity and a little higher enantioselectivity than BINOLs.
