, p. 76 - 79 (1995)
Some quaternary salts of asymmetric substituted pyridines with functional group at the 3- and 5-positions have been synthesized.It has been established that when there is an ester group present, the latter participates in the recyclization of the salts on
Intermolecular [2 + 2] Cycloaddition of 1,4-Dihydropyridines with Olefins via Energy Transfer

A highly regio- and diastereoselective visible-light-promoted [2 + 2] cycloaddition between readily available 1,4-dihydropyridines and olefins has been developed. This strategy is operationally simple and atom-economical and enables the construction of strained polysubstituted 2-azabicyclo[4.2.0]octanes with three all-carbon quaternary centers with good functional group tolerance. These products can be easily converted to various structurally unique derivatives. The primary mechanistic studies demonstrated that the reaction proceeds through an energy transfer pathway.

3-Carbamoyl derivatives of 4-phenyl-5-ethoxycarbonyl-2,6-dimethyl-1,4-dihydropyridine were obtained by cyclocondensation of 2-benzylideneacetoacetic ester with β-aminocrotonic acid amide or anilides.In the alkylation of 4-phenyl-5-ethoxycarbonyl-2,6-dimet
