Claims
- 1. A composition of matter containing a compound of the formula: ##STR29## or enantiomers or racemates thereof in admixture with a compound of the formula: ##STR30## or enantiomers or racemates thereof, wherein R.sub.15 taken together with its attached ##STR31## is a radical derived from a conventional aromatic per-organic carboxylic acid by removal of the hydroxy of the per-carboxylic acid group; R.sub.12 " is lower alkanoyloxy, benzoyloxy, benzyloxy, benzhydryloxy, tetrahydropyranyloxy, 4-methoxy-5,6-dihydro-2H-pyranyloxy, or trimethyl silyloxy.
- 2. The composition of claim 1 wherein R.sub.15 is m-chlorophenyl.
