Sulfur-containing Pyridine Derivatives. LVI. Smiles Rearrangement of Pyridine Derivatives and Synthesis of Benzopyrido-and Dipyrido-1, 4-thiazine Derivatives. (4).

Abstract

1) General considerations were made concerning the mechanism of Smiles rearrangement of pyridine derivatives as a result of further investigation of reaction conditions employed. 2) A 10-substituted dipyrido-1, 4-thiazine derivatives were synthesized with a view to investigating pharmacological action analogous to chlorpromazine.
