The quinoline antibiotics aurachins C, D, and L, and a structurally simplified analog of aurachin C were synthesized from 1-(2-nitrophenyl)butane-1,3-dione via reductive cyclizations of δ-nitro ketone intermediates, with zinc or iron as key steps. The results of antimicrobial tests indicate that the N-hydroxyquinolone nucleus mimics the electron carrier in the respiratory chain more strongly than the

Aurachins, a family of isoprenoidquinolinealkaloids isolated from the myxobacterium Stigmatella aurantiaca, possess multiple interesting bioactivities and were subject of intensive studies of biosynthesis. In this Letter, we describe the efficient few step total synthesis of the parent compound aurachin D and two isoprenoid analogues via Conrad–Limpach cyclization. The main antimicrobial and cytotoxic
