A process for the preparation of substituted 3-(1-amino-2-methylpentane-3-yl)phenyl compounds which has advantages over conventional processes with respect to higher conversions and yields, flexibility, a shorter overall route, environmentally acceptable conditions, influence of stereoselectivity such as diastereoselectivity in a targeted manner and at least partial suppression of the formation of undesired side-products and/or undesired stereoisomers, in particular undesired diastereomers.
一种制备取代的3-(1-氨基-2-甲基戊烷-3-基)苯基化合物的方法,相对于传统方法具有更高的转化率和产率、更大的灵活性、更短的总路线、环境可接受的条件、对立体选择性的影响,例如以定向方式进行对映选择性,以及至少部分抑制不良副产物和/或不良立体异构体的形成,特别是不良对映异构体。
