A new series of 1, 4-dihydropyridines (1, 4-DHPs) endowed with ester groups bearing long and functionalised alkoxy chains at the C3 and C5 positions of the nitrogen ring have been prepared from the corresponding β-keto esters which were in turn prepared by a lipase catalysed transesterification reaction. The structural study has been carried out by X-ray crystallography and theoretical calculations at the semiempirical (AM1), ab initio (HF/6- ...
