  Synthesis of Amino-Benzothiaoxazepine-1,1-dioxides Utilizing a Microwave-Assisted, S_NAr Protocol

  摘要：

  The development of a microwave-assisted, intermolecular SNAr protocol for the synthesis of a 126-member benzothiaoxazepine-1,1-dioxide library is reported. Diversification of 12 benzothiaoxazepine-1,1-dioxides was achieved in rapid fashion utilizing a variety of 2 degrees amines; and amino alcohols to generate an 80-member library. A second 48-member library was subsequently generated via a two-step alkylation, intermolecular SNAr diversification protocol.

  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
