A highly useful method for the stereoselective synthesis of (Z)-α-haloacrylates from various aldehydes that uses α-halogenated ethyl-C,O-bis(trimethylsilyl)ketene acetals in the presence of a Lewis base catalyst such as acetate salts was established. This
New synthetic approach to α-chlorocinnamates: First example of synthesis of functionally substituted alkenes using catalytic olefination reaction

, p. 573 - 577 (2007/10/03)
A new simple and efficient transformation of carbonyl compounds to α-chlorocinnamates is described. Catalytic olefination reaction with ethyl trichloroacetate gives target alkenes in moderate to good yields. The reaction with aromatic aldehydes proceeds stereoselectively to form preferably Z-isomers.
ADDITION OF SODIUM BISULFITE TO DERIVATIVES OF ETHYL ESTERS OF α-SUBSTITUTED CINNAMIC ACIDS
Samarenko, V. Ya.,Markova, N. R.,Passet, B. V.
, p. 122 - 127 (2007/10/02)
The reaction of derivatives of ethyl esters of α-substituted cinnamic acids with sodium bisulfite under conditions excluding radical addition gave the corresponding derivatives of 2-R-substituted sodium 1-phenyl-2-ethoxycarbonyl-1-ethanesulfonates.The eff
