Abstract
Combining natural product fragments to design new scaffolds with unprecedented bioactivity is a powerful strategy for the discovery of tool compounds and potential therapeutics. However, the choice of fragments to couple and the biological screens to employ remain open questions in the field. By choosing a primary fragment containing the A/B ring system of estradiol and fusing it to nine different secondary fragments, we were able to identify compounds that modulated four different phenotypes: inhibition of autophagy and osteoblast differentiation, as well as potassium channel and tubulin modulation. The latter two were uncovered by using unbiased morphological profiling with a cell-painting assay. The number of hits and variety in bioactivity discovered validates the use of recombining natural product fragments coupled to phenotypic screening for the rapid identification of biologically diverse compounds.

Abstract
Discovering novel synthetic routes for rigid nitrogen-containing polyheterocycles using sustainable, atom-economical, and efficient (= short) synthetic pathways is of high interest in organic chemistry. Here, we 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.
