indium-mediated allylation reaction for the synthesis of carbohydrate structures containing the 3-deoxy-2-ulose motif, a barely investigated compound class. The stereoselective outcome can be controlled by the presence or absence of a chelating group in α-position to the carbonyl function. By introduction of an UV-active allyl building block, we enabled epimer separation by HPLC towards the synthesis of 3-deoxy-
摘要我们利用铟介导的烯丙基化反应合成了含有3-deoxy-2-ulose基序的碳水化合物结构,而该结构几乎没有被研究过。立体选择性的结果可以通过在羰基功能的α位上存在或不存在螯合基团来控制。通过引入UV活性烯丙基积木,我们启用差向异构体的分离用HPLC对合成3-脱氧D-甘油基- d -半乳-2- nonulose,广泛分布3-脱氧的羧基还原类似物d -甘油基- d -半乳糖-nonulosonic酸(KDN)。引入的2- C的臭氧分解-亚甲基丙烷-1-醇基序提供了所需的3-脱氧-2-酮糖。 图形概要
