In the course of developing novel antioxidants, we synthesized four of 6-hydroxy-7-methoxy-4-oxochroman-2carboxylic acid dialkylamides (3a-d) $(13{\sim}18%)$ and four of 6-hydroxy-7-methoxychroman-2-carboxylic acid dialkylamides (4a-d) $(52{\sim}89%)$, incorporating the basic amine functionality. None of these compounds exhibited significant antioxidant activity possibly due to the hydrophilic character of the basic amine side chains.
