  One-Pot Syntheses of Pseudopteroxazoles from Pseudopterosins: A Rapid Route to Non-natural Congeners with Improved Antimicrobial Activity

  摘要：

  Rapid one-pot methodologies to prepare pseudopteroxazole (1) and novel congeners from abundant natural pseudopterosins have been devised. This is highlighted here with the first synthesis of the marine natural product homopseudopteroxazole (2) utilizing a novel, silver(I)-mediated catechol to benzoxazole transformation. Pseudopteroxazoles and isopseudopteroxazoles exhibit potent activity against a range of important Gram-positive pathogens including Mycobacterium spp. and vancomycin-resistant Enterococcus faecium. Several non-natural pseudopteroxazoles exhibited strong activity against methicillin-resistant Staphylococcus aureus, thereby displaying a broader spectrum of antibiotic activity compared to pseudopteroxazole.

  New methods of converting pseudopterosins to pseudopteroxazoles have been developed and used to make several new non-natural pseudopteroxazole analogs. These as well as pseudopterosins and derivatives thereof and prenylated aromatic structural mimics of pseudopterosins/pseudopteroxazoles are shown to display anti-bacterial activity including that against non-replicating mycobacteria, with some exhibiting no or limited toxicity against mammalian cells.
