Hydroxy benzothiazepinones were synthesized by a simple procedure involving epoxidation of polymer bound cinnamic acids followed by nucleophilic opening of the resulting glycidic ester by o-aminothiophenol to afford the intermediate hydroxy anilino-esters which underwent cyclization cleavage on heating in DMF to release the product completely.

The preparations and characterisations of a range of lanthanoid 4-(R)-substituted (4-Rcinn, R = OH, OMe, NO2, Cl), known to have good anticorrosion properties, are reported. The crystal structure of [Ce(4-OHcinn)3(MeOH)2(H2O)]·MeOH is a polymer, in which the cerium atoms are nonacoordinate, and adjacent cerium atoms are bridged by either two bridging bidentate or two bridging tridentate carboxylate
