METHOD FOR THE PRODUCTION OF OXAZOLES BY CONDENSING AROMATIC ALDEHYDES WITH alpha;-KETOXIMES TO N-OXIDES AND THEN REACTING THE SAME WITH ACTIVATED ACID DERIVATIVES

摘要

Disclosed is a method for producing oxazoles of formula IV by condensing aromatic aldehydes with a-ketoximes to N-oxides and then reacting the same with activated acid derivatives. The invention relates to a method for producing oxazoles by condensing aldehydes with a-ketoximes to N-oxides in the form of the salts thereof or as free bases and then reacting the same with activated acid derivatives so as to obtain oxazoles in the form of the salts thereof or as free bases.
