The synthesis of a series of ring-methylated 1-alkyl-1,4-dihydronicotinamides and the corresponding pyridinium salts is described.Their NMR properties involving aromatic-ring-shielding anisotropy, due to ring current effects, are discussed and compared with electron populations calculated from STO-3G results.

A method is described for the oxidation of some 1-alkyl-3-carbamoylpyridinium chlorides by reaction with immobilized rabbit liver aldehyde oxydase.With the 1-methyl-, 1-ethyl- and 1-n-propyl derivatives, only the 1-alkyl-1,6-dihydro-6-oxo-3-pyridinecarboxamides have been obtained, but with the t-Bu analogue the corresponding 4-oxo compound was found as single product.The i-Pr derivative gave rise to a mixture of the corresponding 4- and 6-oxo compounds.From the kinetic data some information has been acquired with respect to the enzyme active-site environment and the binding of the substrates to the enzyme.
