Concise enantioselective syntheses of quinolactacins A and B through alternative winterfeldt oxidation

Enantioselective total syntheses of (+)-quinolactacin B and (+)-quinolactacin A2 through asymmetric Pictet-Spengler cyclization and KO2 oxidation-an alternative Winterfeldt condition-are described.

An expedient synthesis of (+)-quinolactacin A2

An expedient synthesis of quinolactacin A2 from N-methylisatoic anhydride and N-Boc-(2S,3S)-isoleucine has been achieved. The key step involves the Friedl?nder-type annulation of isatoic anhydride and β-ketoester derived from isoleucine.

Engineered Biosynthesis of Fungal 4-Quinolone Natural Products

Quinolone-containing natural products are widely found in bacteria, fungi, and plants. The fungal quinolactacins, which are N-methyl-4-quinolones, display a wide spectrum of biological activities. Here we uncovered a concise nonribosomal peptide synthetase pathway involved in quinolactacin A biosynthesis from Penicillium by using heterologous reconstitution and in vitro enzymatic synthesis. The N-desmethyl analog of quinolactacin A was accessed through the construction of a hybrid bacterial and fungi pathway in the heterologous host.
