© 2017 American Chemical Society. 5-Substituted-2-ethoxy-1,3,4-oxadiazoles were conveniently prepared through a one-pot sequential N-acylation/dehydrative cyclization between ethyl carbazate and N-acylbenzotriazoles in the presence of Ph 3 P-I 2 as a dehydrating agent. Subsequent treatment with a s...
