Scope and Limitations in the Synthesis of Glucosamine‐based Ionic Liquids

This research article focuses on the synthesis of ionic liquids from glucosamine, a renewable material obtained chitin. Our group previously experienced some obstacles in these glucosamine-based liquids, often due to sterical hindrance induced by dimethylated amino-group. In this work we present method using Borch reductive amination overcome limitations achieve dimethylethylamino-group. We furthermore expanded upon library with new glycosidic groups, discovered shortened reaction procedure skipping deprotection step and finally compared thermal properties products get an insight into structure-property relationships.
