1H, 13C and 15N NMR spectra of the ring-substituted N-phenylglycines (1) and their ethyl esters (2) were measured in The chemical shift determinations and assignments are based on modern inverse 2D DMSO-d 6 . techniques (HMQC, HMBC). Dependences between chemical shifts and substituent constants sho
Methyl b-substituent e β ects on 17O chemical shifts in dicoordinated oxygen atoms in compounds of the type are found to be insensitive to the nature of the X substrate, even for strongly conjugating CH 3 ΓOΓX groups. Such behavior is rationalized in terms of intramolecular electron delocalizing usin
