Switchable solvent-controlled divergent synthesis: an efficient and regioselective approach to pyrimidine and dibenzo[ b , f ][1,4]oxazepine derivatives

Herein an efficient and regioselective method for the divergent synthesis of pyrimidine and dibenzo[ b , f ][1,4]oxazepine (DBO) derivatives from the same starting materials was developed. The selectivity can be rationally tuned via the judicious choice of reaction solvents. With 1,4-dioxane used as...
