Synthesis of Amino-Benzothiaoxazepine-11-dioxides Utilizing a Microwave-Assisted SNAr 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° 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.
