alpha-anomer of a furanoid sugar-aza-crown ether was developed by a one-pot reductive amination of an alpha-anomer C-ribosyl azido aldehyde. In addition, the beta-anomer furanoid sugar-aza-crown ether was synthesized from a linear disaccharide precursor via amidation and then followed by microwave-assisted amide reduction.
通过一锅还原α-异头异构体C-核糖基叠氮基醛的胺化反应,开发了一种短而高效的途径制备呋喃糖-氮杂-冠冕醚的α-异头物。另外,通过酰胺化由线性二糖前体合成β-端基呋喃糖-氮杂-冠醚,然后进行微波辅助酰胺还原。
