Mix and match: Similar to a galaxy consisting of millions of stars, a multicomponent reaction (MCR) system can result in millions of compounds. The MCR of α‐amino acids, oxo components, isocyanides, and amines leads to numerous and diverse compounds, thus having enormous potential for drug discovery or catalyst screening.

visible‐light‐induced trifluoromethylation of isonitrile‐substituted indolederivatives has been developed from the reaction of isonitrile‐substituted indoles with Togni II reagent, affording 1‐(trifluoromethyl)‐4,9‐dihydro‐3H‐pyrido[3,4‐b]indoles in moderate to good yields. The further transformations to β‐carboline derivatives and a harmacine derivative have been performed, demonstrating the potential synthetic

Physicochemical property switching of chemical space is of great importance for optimization of compounds, for example, for biological activity. Cyclization is a key method to control 3D and other properties. A two-step approach, which involves a multicomponent reaction followed by cyclization, is reported to achieve the transition from basic moieties to charge neutral cyclic derivatives. A series

novel reaction produces α-tetrazolyl N-heterocycles directly from N-heterocycles without involving pre-functionalization/pre-oxidation steps. Importantly, the stereoselective reaction involving chiral amines or chiral isocyanides allowed the expeditious syntheses of nucleoside analogs and α-tetrazolyl pyrrolidine in enantioenriched form.
oles. The reaction is very versatile and good to high yielding. A one-pot, two-step procedure is given. We describe the hitherto unknown use of N-Boc-protected hydrazine in the Ugi tetrazole reaction to access a library of highly substituted 5-(hydrazinomethyl)-1-methyl-1H-tetrazoles. The reaction is very versatile and good to high yielding. A one-pot, two-step procedure is given.
