Configuration d'esters dérivés d'acides 2-fluoro-2-phénylacétique phényles substitués, par RMN du fluor
摘要:
The F-19 NMR chemical shifts (delta(F)) of the p-ZPhCHFCO2CHL1L2 esters of 2-fluoro-2-substituted aryl acetic acids have been measured. The delta(F) values of the two diastereoisomers of these esters are linearly related to the delta+ Brown-Okamoto substituent parameters for each term of the series studied. The configuration of such ester of arylacetic acid can be deduced from their delta(F) values when compared to those of esters derived from the non-substituted acid of known configuration.
