Zhang, Bidong;Kurpiewska, Katarzyna;Doemling, Alexander research published 《 Highly Stereoselective Ugi/Pictet-Spengler Sequence》, the research content is summarized as follows. Discovering novel synthetic routes for rigid nitrogen-containing polyheterocycles using sustainable, atom-economical, and efficient (= short) synthetic pathways is of high interest in organic chem. Here, authors describe an operationally simple and short synthesis of the privileged scaffold dihydropyrrolo[1,2-a]pyrazine-dione from readily accessible starting materials. The alkaloid-type polycyclic scaffold with potential bioactivity was achieved by a multicomponent reaction (MCR)-based protocol via a Ugi four-component reaction and Pictet-Spengler sequence under different conditions, yielding a diverse library of products.
