A new visible light‐induced method is reported for the C3‐alkylation of imidazo[1,2‐a]pyrimidines and ‐pyridines with aryldiazoacetates. This protocol can be performed in open air and serves as a convenient entry to several known and new molecules. A formal synthesis of zolpidem is achieved by changing the alkylating agent to an appropriate hypervalent

Trifluoroacetyl‐substituted D–π–A fluorophore, featuring relatively extended and planar conjugated structure with piperidyl donor and trifluoroacetyl acceptor, demonstrated strong solvatochromism and giga Stokes shifts. This unique and strong acceptor has possibilities to achieve the design of fluorophore for various application, represented by ...
