Abstract
Verbenone 1 or 2 is converted in three steps to ipsdienol 9 or 10 respectively. The diastereoisomeric 2(10)‐pinen‐4‐ols 6 and 7 (or 5 and 8), wich have identical chirality at the carbon atoms bearing OH groups, afford ipsdienol 10 (or 9 respectively) with the same optical purity as the starting material.

The 1,4,5-tris-, 1,3,4-tris-, and 1,3,4,5-tetrakis-phosphates of lo-myo-inositol have been prepared in their enantiomerically pure forms from the two enantiomers of 1,2:5,6-di-O-cyclohexylidene-myo-inositol. A facile enzymic preparation is also described of these chiral intermediates through enantio
