THE STEREOCHEMISTRY OF THE PIMARIC ACIDS

Abstract
Isodextropimaric and dextropimaric acids have been shown to have the same stereochemistry at C1, C11, and C12, but to be epimeric at C7. A critical survey is made of the present evidence with regard to the stereochemistry at C13 in these acids. Preliminary experiments on the action of formic acid on isodextropimaric acid are reported.
