3-Aryloxyproionic acids undergo intramolecular cyclization in the presence of AA.Mont.K-10 in toluene under reflux for 30–45 min in good to excellent yields. Phenyl ring bearing various substituents at the ortho, meta, para positions undergo this cyclization reaction. This method involves simple work up and amenable for large scale preparations. The heterogeneous acid treated catalyst can be regenerated and used for up to three cycles with minimum loss of activity.

A series of some thiazole derivatives were designed and synthesized. The structure of newly synthesized compounds was characterized by HRMS, 1H NMR and 13C NMR. The synthesized compounds were evaluated against ten species of fungi in vitro by agar cup plate and micro-titration methods, respectively. The results of antifungal screening reveal that among all the compounds screened three compounds showed moderate antifungal activity. The MIC value of 3 h against two fungal strains C. neoformans and C. albicas is 8 μg mL-1 respectively. The MIC value of 3i against two fungal strains C. neoformans and T. mentagrophytes is 8 μg mL-1 and 16 μg mL-1, respectively and 3a against T. mentagrophytes is 16 μg mL-1, the MIC of others are all beyond 32 μg mL-1.
