(R)-1-[3,5-Bis(trifluoromethyl)phenyl]ethanol Chemical Properties,Usage,Production

Uses

(R)-[3,5-bis (trifluoromethyl) phenyl] ethanol is an important chiral intermediate for the synthesis of novel chemotherapeutic and antiemetic drugs NK-1 receptor antagonists. Antidepressants have good potential efficacy in treating a range of central and peripheral nervous system depressions.

Preparation

At present, the methods for preparing optically pure (R)-[3,5-bis (trifluoromethyl) phenyl] ethanol include chemical methods and biological methods. Chemical synthesis requires the use of expensive transition metal Ru and other chemical catalysts, complicated steps, harsh reaction conditions, high energy consumption, large pollution, and low yield. Biological law is the use of free enzymes or whole cells for catalytic preparation. It has the characteristics of mild reaction conditions, high catalytic efficiency, and strong specificity.

Chemical Properties

White fine crystalline powder

Uses

(R)-1-[3,5-Bis(trifluoromethyl)phenyl]ethanol is an intermediate in the synthesis of Aprepitant (A729800), a novel selective neurokinin-1 (NK-1) receptor antagonist. In vitro studies using human liver microsomes indicate that Aprepitant is metabolised primarily by CYP3A4 with minor metabolism by CYP1A2 and CYP2C19, and no metabolism by CYP2D6, CYP2C9, or CYP2E1. Antiemetic.

General Description

(R)-1-[3,5-Bis(trifluoromethyl)phenyl]ethanol is a key intermediate for the synthesis of aprepitant, a potent human neurokinin-1 (NK-1) receptor.
