Aminomethyl derivatives of furancarboxylic acids in the Paal-Knorr reaction
摘要:
Aminomethyl derivatives of furancarboxylic acids react with 1,4-dicarbonyl compounds under Paal-Knorr reaction conditions to form the pyrrole rin-L,. It is found that alpha-aminomethyl derivatives of furan-carboxylic acids react faster than their beta analogs. The carboxy group adjacent to the aminomethyl fragment decelerates the process.
