Abstract
1,4-Dihydropyridines and -pyrimidines can be oxidized conveniently to pyridine and pyrimidine with active MnO2 with or without cleavage of t he 4-substituent. In a TiCl4 catalyzed reaction ortho-Claisen rearrang ement takes place with both 4-(2-allyloxy)phenyl 1,4-dihydropyridines and -1,4-dihydropyrimidines.
