Highly diastereoselective dihydroxylation of 4,5-dihydroxy-2-pentenoate with osmium tetroxide using chiral N,N'-dialkyl-2,2′-bipyrrolidine ligands (1) is described. Either syn or anti selection was achieved for acetate (2d) and methyl ether (2e) by employing the enantiomeric ligands.
描述了使用手性N,N′-二烷基-2,2′-联吡咯烷配体(1)用四氧化对4,5-二羟基-2-戊烯酸酯的高度非对映选择性二羟基化。通过使用对映异构体配体,可以对乙酸盐(2d)和甲基醚(2e)进行顺式或反式选择。
