Synthesis of novel 1,3-oxazole derivatives with insect growth-inhibiting activities

摘要

Straightforward and direct synthesis of 2-substituted-5-oxazolecarbaldehydes was achieved by treating propargylamides with mercury(II)perchlorate as catalyst and ammonium cerium(IV)nitrate as oxidant agent through intramolecular cyclization.These structurally interesting outcomes beneft to synthesize2,5-disubstituted-1,3-oxazoles with armyworm growth regulating activities.
