6c–13c, respectively, which in turn are reduced with LiAlH4 to the title compounds 14–24. The enantiomerically pure triols thus available may be useful as chiral building blocks, as auxiliaries for enantioselective reactions, and as center pieces for chiral dendrimers.
醛醇加合物1A - 13A的[R ,- [R -2(叔丁基)-6-甲基-1,3-二恶烷-4-酮(从3-羟基丁酸),以醛,如先前所描述而获得,非对映异构单被乙酰化或苯甲酰化为相应的酯1B -图5b和图6c - 13C,分别,这又与减少的LiAlH 4的标题化合物14 - 24。因此可获得的对映体纯的三醇可用作手性结构单元,对映选择性反应的助剂和手性树枝状聚合物的中心部件。
