PIDA-Mediated Oxidative C-O Bond Formation: Novel Synthesis of Oxazoles from N-AcylEnamines YunhuiZheng 2013.04.12
Introduction • 1.1 The structure of oxazole • A class of five-member ring, heteroaromatic compounds. • Containing an oxygen atom and a nitrogen atom at the 1 and 3 positions of the ring. • The oxazole moiety is the key structure of a number of natural products.
The oxazole is an important heterocycle and many natural products contain oxazole structure, such as disorazole A and hennoxazole A.
Part C Unexpected Products
Part D Application
Conclusion • The hypervalent iodine reagent, Phenyliodinediacetate (PIDA) was successfully used in the synthesis of oxazoles. • A general methodology for the preparation of oxazoles was developed, which displayed excellent functional group compatibility in this reaction.
