The directing effect of COOEt and CN groups (in position 5 in the oxazole) and CH3 group (in position 2 in the oxazole) in the Diels-Alder reactions of appropriate oxazoles with ethyl propiolate was investigated.It has been stated that CN and CH3 groups favor the formation of the ortho product and COOEt group prefers the formation of the meta product.
