Abstract

Multicomponent reactions (MCRs) represent very interesting tools to reach eco-friendly and sustainable transformations in organic chemistry. In particular, the Biginelli reaction furnishes a very easy approach to the synthesis of a library of biological active compounds in an academic course. Here we describe the realization of several experiments involving the synthesis of potential inhibitors of β-secretase by the Biginelli reaction. All of the obtained compounds were tested with a FRET fluorimetric assay. The experiments were proposed to students either at entry level or during advanced laboratory courses of organic and bioorganic chemistry. The learning objectives at the advanced level were to introduce the students to the practice of combinatorial synthesis and to the evaluation of biological activity of combinatorial libraries by enzyme inhibition assays. The meeting of the learning objectives was probed first by analyzing their daily performance in the laboratory and their increasing proactive attitude, and the contents of their final presentations. The resulting marks obtained by the students were compared with the average evaluation of their career. Second, the students were asked to evaluate the course and their own experience, and the outcome of their evaluation was compared with that of the teachers. © 2021 American Chemical Society.
