Microwave Assisted Efficient Synthesis of Imidazole-Based Privileged Structures

摘要

A simple and efficient microwave assisted synthesis of imidazobenzoxazines, imidazobenzoxazin-5-ones, and imidazobenzoxazin-5-thiones with broad chemistry scope is described. The molecules were prepared both under conventional as well as microwave heating conditions, to provide in high yields with clean and scalable reactions a small library of imidazole-based privileged structures for drug discovery.
