Abstract

Stereoselective Synthesis of Ambiphilic Alkenes via Regioselective Methylation of α-Trifluoromethanesulfonyl Carbonyl Compounds with Trimethylsilyldiazomethane. -Triflyl-substituted enol ethers or ketene aminals are synthesized through a selective O-methylation of the corresponding carbonyl compounds with azo compound (VI). -(KONG, H.
