Abstract

A convenient, direct, one‐pot highly efficient microwave‐assisted synthesis of biomass‐derived D‐glucose‐based hydroxide ionic liquid via a simple three‐step approach has been described. The key features of the method include rapidness, eco‐friendliness, and excellent yields. To the best of our knowledge, this is the first methodology for synthesizing D‐Glucose‐based sugar ionic liquid (GSIL) under microwave irradiation. The developed catalyst allowed us to synthesize diverse dihydropyrano[3,2‐c]‐chromenes upto 95% yield in 30‐90 min stirring at 80 ̊C under mild conditions. The scope of the study was investigated using 30 instances. Developed GSILs exhibited excellent catalytic activity as well as good recyclability. Overall, the catalyst showed excellent value in green chemistry parameters such as atom economy (95%), E‐factor (0.05), carbon efficiency (100%), process mass intensity (1.62), and reaction mass efficiency (0.860).

可持续合成 D-葡萄糖基 IL：高效合成二氢吡喃香豆素的可再生有机催化剂

通过简单的三步法，描述了一种方便、直接、单锅高效的微波辅助合成生物质衍生 D-葡萄糖基氢氧离子液体的方法。该方法的主要特点包括快速、环保和收率高。据我们所知，这是第一种在微波辐照下合成 D-葡萄糖基糖离子液体（GSIL）的方法。所开发的催化剂使我们能够在温和条件下于 80 ̊C 搅拌 30-90 分钟内合成多种二氢吡喃并[3,2-c]-苯并吡喃，收率高达 95%。研究使用了 30 个实例。所开发的 GSIL 具有出色的催化活性和良好的可回收性。总体而言，该催化剂在原子经济性（95%）、E 系数（0.05）、碳效率（100%）、过程质量强度（1.62）和反应质量效率（0.860）等绿色化学参数方面表现出优异的价值。

期刊介绍： Organic chemistry is the fundamental science that stands at the heart of chemistry, biology, and materials science. Research in these areas is vigorous and truly international, with three major regions making almost equal contributions: America, Europe and Asia. Asia now has its own top international organic chemistry journal—the Asian Journal of Organic Chemistry (AsianJOC) The AsianJOC is designed to be a top-ranked international research journal and publishes primary research as well as critical secondary information from authors across the world. The journal covers organic chemistry in its entirety. Authors and readers come from academia, the chemical industry, and government laboratories.
