A process for preparing an o-iminooxymethylbenozic acid of the general formula I ##STR1## comprises reacting an oxime of the general formula II ##STR2## with a lactone of the general formula III ##STR3## if appropriate in the presence of a base or of a diluent, and o-iminooxymethylbenzoic acids of the abovementioned formula.

o-Iminooxymethylbenozic acids of the general formula I ##STR1## are disclosed where, m, X, R.sup.1 and R.sup.2 are defined herein.

Sterically pure .beta.-triazolyl carbinols of the general structure ##STR1## where R is not hydrogen, in particular the R*, S*-diastereomer, are obtained by diastereoselective reduction of the corresponding .alpha.-triazolylketone with a complex hydride which reduces ketones to alcohols, in the presence of a Lewis acid in a non-polar solvent.

A mixture of (R)- and (S)-2-(4-alkanoylphenoxy)- or (R)- and (S)-2-(4-aroylphenoxy)propionic esters I ##STR1## with an enantiomeric excess of at least 90% is prepared by reacting a mixture of (R) and (S) enantiomer of a 2-phenoxypropionic ester II ##STR2## in which the appropriate (R) or (S) isomer is present in excess, with a carboxylic acid derivative of the formula III (X=OH, halogen, R.sup.1 COO or sulfonyloxy) in the presence of a Friedel-Crafts catalyst. The (R)- or (S)-2-(4-alkanoylphenox…
