Patent

CA 2192417

This invention relates to processes for asymmetrically producing enantiomerically pure .alpha.- cycloalkylalkyl substitututed methanamines from .alpha.-pinene. One key step of the process of this invention utilizes the oxidation product of .alpha.-pinene, hydroxy pinanone, as a chiral auxiliary to direct the stereoselective alkylation of the corresponding ketimine. This invention also relates to key intermediates useful in the processes referred to herein.
