Labeling experiments confirmed their structures and gave initial evidence for a novel biosynthesis pathway of these natural oxazoles. In order to confirm their structure, they were synthesized, which also allowed tests of their bioactivity. Additionally, the bioactivities of the synthesis intermediates were also investigated revealing interesting biological activities for several compounds despite their overall simple structures. © 2012 The Surface Science Society of Japan.Mahidol UniversityChemistryArticleSCOPUS10.3762/bjoc.8.85
