THE STEREOCHEMISTRY OF THE PIMARIC ACIDS

Abstract

Isodextropimaric and dextropimaric acids have been shown to have the same stereochemistry at C 1 , C 11 , and C 12 , but to be epimeric at C 7 . A critical survey is made of the present evidence with regard to the stereochemistry at C 13 in these acids. Preliminary experiments on the action of formic acid on isodextropimaric acid are reported.
