A solvent-free approach for the regioselective synthesis of beta-amino alcohols in shorter reaction times and higher yields, compared to conventional heating is described. It involves microwave (MW) exposure of undiluted reactants in the presence of sulphated zirconia (SZ) or sulphated zirconia over MCM-41 (SZM) as catalyst. Both acid materials can be easily recovered and reused.
本文描述了一种无溶剂方法，与传统加热相比，该方法能在更短的反应时间内以更高的产率区域选择性合成β-氨基醇。该方法包括在硫酸化氧化锆（SZ）或负载于MCM-41上的硫酸化氧化锆（SZM）作为催化剂存在的情况下，对未稀释的反应物进行微波（MW）辐照。两种酸性材料都能很容易地回收和重复使用。
