Product name:(1R, 2S)-(-)-2-Amino-1,2-Diphenylethanol

CAS
:23190-16-1

Molecular Formula:C14H15NO

Formula Weight:213.27g/mol

Description:Melting point is 142-144 ºC.The cyclization of (1S,2R)-2-amino-1,2-diphenylethanol (XVII) with trichloromethyl chloroformate and triethylamine in dichloromethane gives (4R,5S)-4,5-diphenyloxazolidin-2-one (XVIII), which is treated with 1,1-dimethoxyethane and an acid catalyst, yielding the 1-methoxyethyl derivative (XIX). The heat treatment (150 C) of (XIX) affords the corresponding vinyl derivative (XX), which is cyclized with fluorodiiodomethane and diethyl zinc (a fluorocarbenoid compound) in a preferentially cis-way to afford the cyclopropyl-oxazolidinone (XXI), purified by column chromatography.
