摘要

1. New phenolic compounds of formula (I) (CF DRAWING IN BOPI) - R = dialkoxymethyl group at C3 -C17, dioxolan group -1.3 yl-2 optionally substituted on the vertices 4 and / or 5 by one or more alkyls in C1 -C8 or dioxan-1,3 yl-2 group optionally substituted on the vertices 4 and / or 5 and / or 6 by one or more C1 -C8 alkyls. - n = 1, 2 or 3, the group (s) (CF DRAWING IN BOPI) are in position o and / or p of the OH of the cycle- m = from 0 to 4-n, X = functional group such as OH or Hal or C1 -C8 alkyl or alkoxy group or C5 -C12 aryl and optionally 1 or 2 heteroatoms such as N or O, or carboxy or -CO-Y where Y = C1 -C8 alkyl or alkoxy or amido or amino or thiol, provided that at least one of the ortho or para positions of the phenolic ring is substituted by hydrogen, as well as their salts with alkali metals, alkaline earth metals and amines.
