| | 2-Picolylamine Usage And Synthesis |
| Description | It is usually used as the intermediate or raw material in the organic synthesis and pharmaceutical synthesis. For example, this chemical can promote the Al(OTf)3-catalyzed aminolysis of 1,2-epoxides to produce β-Amino alcohols N-2'-pyridylmethyl in excellent yields.1 Moreover, this substance may function as the raw material to produce copper(Ⅱ) complexes with sulfonamides that act as the active chemical nucleases.2 In addition, by using this chemical as substrate, an efficient [2+3] cycloaddition approach has been developed for the synthesis of pyridyl-appended fullerene ligands.3 Besides, 2-picolylamine is chosen as the recognition group to get better selectivity for a rhodamine-based “turn-on” fluorescent probe for Fe3+ in aqueous solution.4
