TRANSFORMATIONS OF PYRIDINIUMS DERIVED FROM AMINO-ALCOHOLS AND FROM DIAMINES

Pyridiniums derived from amino alcohols cyclise to ethers or rearrange to aldehydes on heating.Monopyridiniums from diamines can be acylated or converted into ureas or thioureas: these products cyclise on heating in solution to give dihydro-thiazoles, -4H-thiazines, -oxazoles, -4H-oxazines, or tetrahydro-3H-thiazepines.
