New derivatives of cromonas, their process of synthesis and their use as antioxidant / preservatives

摘要

This invenu00c7u00c3o relates to the obtaining of new cromonas amides, with the following general follow a and B, in which R1 and R2 represent respectively: R1 = R2 = h; R1 = h, R2 = Oh; R1 = Oh, R2 = OCH3; R1 = R2 = OCH3; R1 = R2 = Oh.These new compounds with different replacement standards, were obtained through a reaction between the 3 - condensau00c7u00c3o carboxicromona or 2 - carboxicromona and aniline (fenilamina), or its derivatives replaced, with income apreciu00c1veis. The obtaining of Di hydroxylated derivatives was carried out by a reaction of desmetilau00c7u00c3o of cromonas monometoxiladas.Some of these compounds have application as antioxidants / preservatives in the pharmaceutical, cosmu00c9tica and / or food.
