highly efficient continuous‐flow process has been developed for the synthesis of diazoesters from arylsulfonylhydrazones by means of in‐flow Bamford–Stevens reactions. Furthermore, a range of α‐alkoxy and α‐amino acid derivatives have been prepared in excellent yields through rhodium(II)‐mediated OH and NH insertions, without the need to isolate or handle the potentially hazardous diazo species (see
