Carbon-13 chemical shifts have been measured of para-substituted 3-phenyl propanoic acid methyl esters. The substituent-induced 13C shifts of the side chain were related to Hammett substituent effects by the dual substituent parameter method. The transmission of substituent effects and the factors that influence 13C shifts are discussed

Synthesis and detailed spectral analysis of a new 4-substituted coumarin-amino acid derivate are presented in this paper. A new glycine derivate of (3-nitro-2-oxo-2H-chromen-4-yl)amino]acetate was prepared by condensation of 4-chloro-3-nitrocoumarin and ethyl glycinate hydrochloride. The complete assignment of 1H and 13C NMR chemical shifts of the synthesized compound was carried out by the aid of a combination of 1D (1H and 13C NMR) and 2D (1H-1H-COSY, NOESY, HSQC and HMBC) NMR experiments.
