Synthesis, Structure and Antifungal Activity of New 3-[(5-Aryl-1,3,4-oxadiazol-2-yl)methyl]benzo[d]thiazol-2(3H)-ones

“…Traditionally, they can be prepared by cyclization of the corresponding acyclic semicarbazide or thiosemicarbazide derivatives using a variety of reagents, including POCl 3 [ 11 ], PCl 5 [ 12 ], PPA [ 13 ], (CF 3 CO) 2 O [ 14 ] and so on. Nowadays, new synthetic approaches to 1,3,4-oxadiazoles have been developed, such as microwave assisted synthesis [ 15 ], solid phase synthesis [ 16 ], Pd-catalyzed [ 17 ] and solvent-free [ 18 ] methods.…”
