Continuous multistep synthesis of 2-(azidomethyl)oxazoles
Beilstein Journal of Organic Chemistry, 2018 An efficient three-step protocol was developed to produce 2-(azidomethyl)oxazoles from vinyl azides in a continuous-flow process. The general synthetic strategy involves a thermolysis of vinyl azides to generate azirines, which react with bromoacetyl ...

Identification and isolation of insecticidal oxazoles from Pseudomonas spp. [PDF]
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 ...
