moderate growth inhibition against Candida species. 1,3-Benzoxazole-4-carbonitrile 6 showed potent activity against Candida species compared to 5-desmethyl compound 4 and triazolopyridine 2. Compound 6 was efficiently prepared from versatile intermediate 24, which possessed six different substituents on the benzene ring. Conversion of benzene 24 into various 1,3-benzoxazole derivatives such as 2-aliphatic
