We report the synthesis of 1,4-dihydropyridines on solid support utilizing the Hantzsch condensation. Unwanted reactive impurities were removed from the desired products, by selective cleavage from solid support. The synthesis of a 272 compound library is reported using the methods described.

## Abstract The U.V. and I.R. spectral data of 4‐aryl‐3,5‐diethoxycarbonyl‐2,6‐dimethyl‐1,4‐dihydropyridines with different aryl substituents are discussed. The Ξ»~max~ values of the long‐wavelength absorption band in the U.V. spectra show a similar solvent dependence for all the compounds. (The res
