A new synthetic approach to α-chlorocinnamaldehydes

Nenajdenko, Valentine G.,Reznichenko, Alexander L.,Lenkova, Olesya N.,Shastin, Alexey V.,Balenkova, Elizabeth S.

, p. 605 - 609 (2007/10/03)

A new simple and efficient transformation of aromatic aldehydes into α-chlorocinnamaldehydes is described. Catalytic olefination reaction of hydrazones of aromatic aldehydes with 2-trichloromethyl-1,3-dioxolane gives ethylene acetals of target alkenes in moderate to good yields. The reaction proceeds stereoselectively to form preferably Z-isomers.
