产品说明

一般描述

Polymer-bound 4-(dimethylamino)pyridine is used for improved derivatization of chiral and achiral aliphatic amines, amino alcohols and amino acids.

应用

Polymer-bound 4-(dimethylamino)pyridine is used as a supported base in the Michael addition and nitrous acid elimination process step involved in the synthesis of thiophene-2-carboxylates using β-nitroacrylates as starting materials, under a general and efficient continuous flow-based protocol. It also serves as a supported catalyst in the preparation of ω-nitro esters starting from cyclic 2-nitro ketones under solid heterogeneous catalysis.(5)
