  The determinations of product structures obtained in the microbial hydroxylations of various 2-cycloalkyl-1, 3-benzoxazoles using Cunninghamella blakesleeana DSM 1906 and Bacillus megaterium DSM 32 are described. The initially low e.e. of 3-(benz-1, 3-oxazol-2-yl)cyclopentan-1-ol 6, 2-(benz-1, 3-oxazol-2-yl)cyclohexan-1-ol 14 and 4-(2-bent-1, 3-oxazol-2-yl)cycloheptan-1-ol 21 can be enhanced to 98% using lipase catalyzed resolution.

  The synthesis of a new series of 2,5-disubstituted benzoxazoles 4a-f, 2-substituted oxazolo(4,5-b)pyridines 5a, b, benzothiazoles 6a, b and benzimidazoles 7a, b is described in order to determine their antimicrobial activities and feasible structure-activity relationships (SAR). The synthesized compounds were tested in vitro against 3 Gram-positive, 3 Gram-negative, and a fungus Candida albicans. 4b, 4e and 4f were found to be more active than the others against Klebsiella pneumoniae at a MIC value of 12.5-mu-g/ml. All the derivatives 4-7 exhibited significant antimycotic activity against C albicans. The antibacterial and antimycotic activities of 4-7 are also compared with several standard drugs.
