Convenient Synthesis of Mixed Anhydrides by the Ozonolysis of Oxazoles

Kashima, Choji,Hibi, Shigeki,Harada, Kazuo,Omote, Yoshimori

, p. 529 - 534 (2007/10/02)

The ozonolysis of azoles was investigated, and the products formed via a 1,2-addition of ozone were the main ones obtained.In particular, 2,5-disubstituted oxazoles (2) were treated with an excess of an ozone-oxygen stream to give the corresponding acid anhydrides (6) quantitatively.This reaction should be useful for the preparation of mixed anhydrides (6) in good yield at low temperature.
