  Synthesis and conformational properties of sugar amides and thioamides

  摘要：

  The synthesis of deoxythioformamido and deoxythioacetamido derivatives of 1,2:3,4-di-O-isopropylidene-alpha-D-galactopyranose, 1,2:3,5-di-O-isopropylidene-alpha-D-glucofuranose and 2,3:4,5-di-O-isopropylidene-beta-D-fructopyranose at the primary carbon atom has been effected by thionation of the corresponding sugar amides. Formamides and thioformamides existed as a mixture of the Z (major) and E (minor) stereomers around the N-C(=X) bond in CDCl3 solutions, while the Z rotamer was the sole one detected in the cases of acetamides and thioacetamides.

  摘要：

  我们应用了多组分方法来访问包含与异亚丙基保护的d-果糖，l-山梨糖，d-半乳糖和d-阿洛糖有关的醛，胺和异氰化物组分的密集功能化的均价和杂多价糖模拟物的库。获得的Passerini产品收率非常高（高达78％）和非对映异构体选择性很高（高达98：2）。通过Ugi反应获得了三种类型的产物。连同“经典的”四组分产物一起，分离出α-酰基氨基酰胺，三组分α-氨基酰胺和四组分α-氨基酰胺。亚胺酸酯中间体的结构合理化了多种途径，主要受胺成分的影响。

  glycomimetics comprising aldehyde, amine, and isocyanide components related to isopropylidene-protected d-fructose, l-sorbose, d-galactose, and d-allose. Passerini products were obtained in very good yields (up to 78%) and high diastereoselectivities (up to 98:2). Three types of products were obtained by the Ugi reaction; along with the "classical" four-component product, α-acylaminoamides, a three-component
