Abstract
The efficiency of the 2-oxazoline system as a protecting group for the sterically hindered carboxyl function is demonstrated in the case of Grignard-reactions of certain organophosphorus compounds. Thereby, organophosphorus species with an o-carboxyphenyl group are easily accessible. Additionally, the enantiomer separation of an unsymmetrically substituted tertiary phosphine oxide with an o-carboxyphenyl group is described.
