一般描述

Asymmetric catalytic addition of ethyl groups to 3′-(trifluoromethyl)acetophenone catalyzed by ligands derived from trans-1,2-diaminocyclohexane and camphor sulfonyl chloride has been reported. Phenylation of 3′-(trifluoromethyl)acetophenone in the presence of dihydroxy bis(sulfonamide) ligand (enantioselective catalyst), titanium tetraisopropoxide and diphenylzinc has been investigated.

应用

3′-(Trifluoromethyl)acetophenone has been used in a key step during the preparation of a commercial fungicide.

Many catalysts will promote the asymmetric addition of alkylzinc reagents to aldehydes. In contrast, there are no reports of additions to ketones that are both general and highly enantioselective. We describe herein a practical catalytic asymmetric addition of ethyl groups
