Identification and isolation of insecticidal oxazoles from Pseudomonas spp.

Beilstein Journal of Organic Chemistry, 2012
Two new and five known oxazoles were identified from two different Pseudomonas strains in addition to the known pyrones pseudopyronine A and B. Labeling experiments confirmed their structures and gave initial evidence for a novel biosynthesis pathway of ...
