| Questions And Answer | Back Directory | [Description]
Oxazole is the primary compound for a various class of heterocyclic aromatic organic compounds, which include azoles with a nitrogen and an oxygen separated by one carbon. Oxazole is a weak base and an aromatic compound.
| [Preparation]
There are various methods of synthesizing oxazole in organic chemistry including Van Leusen reaction with TosMIC and aldehydes, Robinson-Gabriel preparation by dehydration of 2-acylaminoketones, and Bredereck reaction with formamide. Oxazole result from the oxidation and cyclization of threonine and serine non-ribosomal peptides.
