title: Dienals derived from pyridinium salts and their subsequent application in natural product synthesis.
abstract: Transformation of quaternary pyridinium compounds into functionalized conjugated dienes can be adapted to natural product synthesis with great effect. Most conspicuously, the transformation has been employed in the preparation of polyenic structures. However, in a more convoluted application, polycyclic systems have arisen from elaboration of the diene motif. The goal of the present account is to survey the utility of dienals derived from pyridinium salts as the means to establish molecular architecture featured in natural products.
