Go with the flow! Using a combination of continuous‐flow techniques and microwave irradiation, a 19‐member collection of 5–10 gram quantities of benzthiaoxazepine‐1,1‐dioxides has been produced (see scheme). The elimination of intermediate‐ and large‐scale process optimization by invoking the concept of scale‐out (rather than scale up) has significantly reduced the time necessary to prepare these compounds
