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.

Abstract: A single-mode microwave cavity synthesizer with temperature and pressure control was used to accelerate the Hantzsch synthesis of 4-aryl and 4-alkyl-2,6-dimethyl-1,4-dihydro-3,5-pyridinedicarboxylates. In comparison with both conventional method
Process for 1,4-dihydropyridine compounds using a titanamine catalyst
-
, (2008/06/13)
A process for the preparation of 1,4-dihydropyridine compounds, especially N-substituted 1,4-dihydropyridine compounds, is disclosed. The compounds are useful as cardiovascular agents and also as starting materials for the preparation of certain cyclized compounds which have properties as calcium entry blockers.
