In this study, we present the development of two catalytic processes: a Pd-PEPPSI-catalyzed aminocarbonylation and a Pd(OAc)-Xantphos-catalyzed alkoxycarbonylation of d-glycals, utilizing carbonylative cross-coupling reactions. We explored successfully various types of aromatic amines, as well as alkyl amines and amino acids, to synthesize new d-glycal amides. However, we observed limitations in the reactivity of alkyl and heteroaromatic amines. The processes enabled the synthesis of 20 novel C1-branched glycoamides and 7 new d-gluco esters.
在本研究中，我们展示了两种催化过程的进展：一种是钯-吡啶双齿膦配体催化剂催化的氨羰基化反应，另一种是醋酸钯-联二萘二苯基膦催化剂催化的d-甘醇的烷氧基羰基化反应，均利用羰基化交叉偶联反应。我们成功探索了各种类型的芳香胺、脂肪胺和氨基酸，以合成新的d-甘醇酰胺。然而，我们观察到脂肪胺和杂芳胺的反应活性存在局限性。这些过程实现了20种新型C1-支链糖酰胺和7种新的d-葡萄糖酯的合成。
