Compounds and methods for preparing substituted 3-(1-amino-2-methylpentane-3-yl)phenyl compounds from an isomerically pure starting material are described. In particular, methods of preparing a 3-(1-(dimethylamino)-2-methylpentane-3-yl)phenol as a substantially optically pure (R,R) stereoisomer are described. Using a method of the present invention, only the (R,R) and (S,S) stereoisomers of the target compound are produced, increasing the yield and stereoselectivity of the desired (R,R) stereoisomer.
本文描述了从具有同分异构体纯度的起始材料制备取代的3-(1-氨基-2-甲基戊烷-3-基)苯基化合物的化合物和方法。特别地,本文描述了制备3-(1-(二甲氨基)-2-甲基戊烷-3-基)苯酚作为实质上光学纯(R,R)立体异构体的方法。使用本发明的方法,只会产生目标化合物的(R,R)和(S,S)立体异构体,从而提高了所需(R,R)立体异构体的产量和立体选择性。
