Abstract

A novel series of 3-acetyl-5-alkyl-1-benzyl-1,4-dihydropyridines (alkyl: methyl; ethyl; isopropyl; n-propyl) is synthesised. 1H-NMR-spectra are discussed. A mass spectral fragmentation is elaborated using high resolution mass measurements, metastable defocusing technique and deuterium labelling.
