Abstract

This paper describes the synthesis of two amino-quinazolinediones which are potent gyrase/topoisomerase inhibitors and useful as antibacterial agents. The early scale-up work to prepare a chiral side chain on multigram scale and two different amino-quinazolinedione cores is detailed. The enabling synthesis for the side chain employed a previously reported Michael addition of MeNO2 to an enantiomerically enriched δ-amino-enoate and a two- ...
