    Notes: A novel method for the synthesis of acid anhydrides is described. Condensation of two molequivalents of a triethylammonium salt of an aliphatic or aromatic acid with one molequivalent of phosgene in an inert solvent at low temperature furnishes excellent yields of anhydrides.

    Notes: A novel method for the resolution of 5-hydroxy-DL-tryptophan is described. Successive treatment of N-Benzyloxycarbonyl-5-benzyloxy-DL-tryptophan with the stereoisomeric bases quinidine and quinine precipitates directly the corresponding salts of the L- and D-antipodes.
