摘要:A process for the preparation of phenyl ketones, characterized in that, in a first stage, a halo- or trihalomethylbenzene is reacted with a trihalomethylated aliphatic or aromatic compound in the presence of boron trifluoride in an amount such that the absolute pressure of boron trifluoride within the reaction vessel exceeds 1 bar, and in the presence of hydrofluoric acid as a solvent, and in that, in a second stage, the resultant product is hydrolyzed. The products are used as intermediates in the synthesis of compounds having a pharmaceutical or phytosanitary (e.g., herbicidal) activity.

标 题:Process for preparing chiral tetralone
发明人：QUALLICH GEORGE J
权利人:PFIZER
摘要:A process for preparing the chiral (4S)-(3,4-dichlorophenyl)-3,4-dihydro-1(2H)-naphthalenone is disclosed wherein racemic 4-(3,4-dichlorophenyl)-3,4-dihydro-1(2H)-naphthalenone is asymmetrically reduced by contacting the racemic tetralone with an asymmetric reagent to produce a mixture of cis and trans alcohols, separating the cis from the trans alcohols, and oxidizing the (4S) enantiomer of the resulting cis and trans alcohols. Also disclosed are novel intermediates used in the synthesis of the above chiral tetralone.
