| Summary: | 1,2,4-oxadiazoles are used in a wide range of applications, including medicinal chemistry and chemistry of materials. However, this kind of oxadiazoles is not usually prepared in an undergraduate organic teaching laboratory. This work describes a didactic sequence for the preparation of 1,2,4-oxadiazols, mediated by microwave irradiation, employing home-use microwave oven. For the development of this practice, one lecture and one laboratory session were used. At the end of this session, a questionnaire was applied to evaluate the didactic sequence. The conclusion was that this approach can be used for the preparation of 1,2,4-oxadiazoles as a pedagogical practice to make the process of teaching easier and enjoyable.
