摘要

本文首次采用酸性壳聚糖（CS-SO3H）作为非均相有机催化剂，研究了一种环境友好、价格低廉、可扩展的不同醇直接法烷基化反应。各种各样的醇可以转化，具有广泛的官能团耐受性和高原子经济性。值得注意的是，催化剂回收和方法的化学选择性也进行了评估。

Direct Lawsone O-Alkylation Employing Sulfonic Acid-Functionalized Chitosan as a Biodegradable Organocatalyst.

An environmentally friendly, cheap, and scalable protocol for direct lawsone O-alkylation employing different alcohols using acid chitosan (CS-SO₃H) as a heterogeneous organocatalyst is described herein for the first time. A wide variety of alcohols can be converted with wide functional group tolerance and high atomic economy. Significantly, catalyst recycling and method chemoselectivity were also assessed.
