据报道由D-葡萄糖醛酸内酯合成差向异构的6 C-丁基葡萄糖。两种完全保护的乳糖醇的硼氢化钠还原是高度立体选择性的,但伴随着甲硅烷基保护基团的迁移。在氯化铈(III)的存在下,立体选择性几乎没有变化,但是甲硅烷基的迁移被抑制。6 R -6 C-甲基葡萄糖和6 R -6 C-丁基葡萄糖都比6 S差向异构体更好地是磷酸葡萄糖变位酶抑制剂。

The synthesis of the epimeric 6C-butylglucoses from D-glucuronolactone is reported. The sodiumborohydride reduction of two fully protected lactols is highly stereoselective but is accompanied by migration of a silyl protecting group; in the presence of cerium(III) chloride, there is little change in the stereoselectivity but the migration of the silyl group is suppressed. 6R-6C-Methylglucose and 6R-6C-butylglucose
