Generation of a configurationally stable, enantioenriched α-oxy-α-methylbenzyllithium: Stereodivergence of its electrophilic substitution

Carstens, Axel,Hoppe, Dieter

, p. 6097 - 6108 (2007/10/02)

The deprotonation of (R)- or (S)-1-phenylethyl N,N-diisopropylcarbamate with s-butyllithium/TMEDA in unpolar solvents (e.g. ether or hexane) at -78°C produces configurationally stable ion pairs which are substituted stereospecifically by different electro
