Five- and six-memberedlactams were synthesized via a 4-center 3-component Ugi reaction by combining amines, isocyanides, and ketoacids under solvent-free microwave conditions. The reaction was carried out in much shorter times and the yields were improved in comparison to classical conditions.

continuous‐flow microfluidic setup enables in situ generation, extraction, separation, and reaction of foul‐smelling isocyanides with little exposure to the surroundings. Isocyanides were generated by dehydration of the corresponding N‐substituted formamides, and several representative isocyanide‐based organic reactions were successfully performed. DIPEA=N,N‐diisopropylethylamine.
