The Stereoselective Construction of (Z)-3-Aryl-2-fluoroalkenoates
Welch, John T.,Herbert, Randal W.
, p. 4782 - 4784 (2007/10/02)
The use of 2,4,6-trimethylphenyl α-silyl-α-fluoroacetate in the Peterson olefination reaction leads to the highly stereoselective formation of (Z)-3-aryl-2-fluoroalkenoates via an aldol reaction most likely proceeding through an open transition state sinc
