A series of PAI have been condensed using trimellitic acid and also 3-amino-4-methylbenzoic acid and various diamines. It was found that the permeability or helium increases with increasing fluorine content. In addition, nonlinear moieties contribute to the permeability. In PAI with oligo(tetrafluoroethene) segments, the substitution patterns of the phenyl group in the diamine moieties do not notably influence the diffusivity." ...

A suspension of 40 g 2-amino-3-methylbenzoic acid methyl ester in 125 ml of benzene was added 125 ml of saturated solution of sodium acetate and then at 0-5°C was added 37 g chloracetylchloride. The mixture was stirred for 1 hour at room temperature. The mixture was filtered. The organic layer was with 10% solution of potassium carbonate and dries under calcium chloride. 

Formation of a peptide bond involves two steps (1) activation of the carboxylic acid, and (2) aminolysis of the activated species. The first step starts with the reaction of the carboxylate ion with the phosphorus atom of the coupling reagent. The resulting acyloxyphosphonium ion 27 (Scheme 10) has only been observed for PyBOP- or PyCloP-mediated activation by using low temperature P NMR experiments and the sterically hindered 2,4,6-tri-methylbenzoic acid.P With N-protected amino acids, the acyloxyphosphonium intermediate reacts to give more stable species, the structure of which depends on the type of the reagent involved (Scheme 11).0 1...

Thioamides have also been used in place of amides for the synthesis of 4-quinazolones. For example, heating 2-amino-5-methylbenzoic acid (41) with thioacetamide (42) at 135-150 °C for 2 h yielded 43 as the product in 73% yield. ...
