Depsides

Amongst other compounds chlorphydroxybenzoic acid is used in the preparation of the materials employed in the synthesis of depsides; the free phenolic group, however, exerts a disturbing influence when aromatic acids are acted upon by phosphorus chloride, and another group, which can subsequently be easily removed, must therefore be introduced to cover the disturbing influence referred to. ❋ Georg Grasser (N/A)

These depsides, however, are amorphous substances, and it is hence difficult to substantiate their homogeneity. ❋ Georg Grasser (N/A)

Monohydroxybenzoic acids allow theoretically of tri-depsides of the type ❋ Georg Grasser (N/A)

The carbomethoxy derivatives of the depsides are as a rule crystalline substances of distinct acidic character, and decompose alkaline carbonates. ❋ Georg Grasser (N/A)

The principles underlying the synthesis of depsides are the following: -- If the chlorides of carbomethoxy (or carbethoxy) hydroxybenzoic acids are coupled with the sodium salts of hydroxybenzoic acids, esters are formed, _e. g. ❋ Georg Grasser (N/A)

The following summary gives an account of depsides which have been prepared synthetically or which occur naturally: -- [Footnote 1: _Ber. ❋ Georg Grasser (N/A)

The depsides thus formed would serve as vehicle of the sugars and transport the migrating tannins, [Footnote: Kraus, "Grundlinien zu einer Physiologie der ❋ Georg Grasser (N/A)
