以甘露醇和山梨醇为原料 ,合成了 2个新的手性膦配体 ,并用这些新的手性膦配体与钯原位生成的催化剂体系催化苯乙烯的不对称氢酯基化反应 ,得到 R构型的 2 -苯基丙酸甲酯 ,其 ee值分别为 2 8.5 %和 13.6 %
Two new chiral phosphine ligands were synthesized from mannitol and sorbitol and the asymmetric hydroesterification of styrene was catalyzed by these new chiral phosphine ligands and the palladium catalyst system formed in situ. The methyl 2-phenylpropionate in the R configuration had ee values of 8.5% and 13.6%, respectively
