标题 :Asymmetric synthesis of α-cycloalkylalkyl substituted methanamines
发明人：ROTH GREGORY; LANDI JOHN
权利人:BOEHRINGER INGELHEIM PHARMA
摘要:This invention relates to process for asymmetrically producing enantiomerically pure α-cycloalkylalkyl substitututed methanamines from α-pinene. One key step of the process of this invention utilizes the oxidation product of α-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.
