presence of Fe(3+)-K-10 montmorillonite clay as a catalyst, aliphaticcarboxylicacidsselectively produced the corresponding esters in the presence of aromatic carboxylicacids by treatment with alcohols. Both the aliphatic and aromatic carboxylicacids formed the amides by reacting with the aliphatic amines, but only the aliphaticcarboxylicacids yielded the anilides by treatment with aromatic amines
effectiveness of radiation. Inspired by hemoglobin allosteric oxygen release regulators, a series of novel phenoxyacetic acidanalogues were designed and synthesized. A numerical method was applied to determine the activity and safety of newly synthesized compounds. In vitro studies on the evaluation of red blood cells revealed that compounds 19c (∆P50 = 45.50 mmHg) and 19t (∆P50 = 44.38 mmHg) improve
