An efficient synthesis of a polymer-supportedHantzsch1,4-dihydropyridineester has been developed and its use in a variety of reduction reactions was studied using α,β-unsaturated aldehydes, imines and an activated benzoquinone as substrates. Reductive amination using the polymer-supportedHantzsch1,4-dihydropyridineester and a catalytic amount of 1.5 M HCl was found to proceed rapidly and with
已经开发出聚合物负载的Hantzsch 1,4-二氢吡啶酯的有效合成方法,并以α,β-不饱和醛,亚胺和活化的苯醌为底物,研究了其在各种还原反应中的应用。发现使用聚合物负载的Hantzsch 1,4-二氢吡啶酯和催化量的1.5 M HCl进行的还原胺化反应迅速进行,并且收率很高。
