A thorough study on the ( E ) to ( Z ) photoisomerization of ferulic acid derivatives (esters, amides of all types, and ketones) was carried out. At the photostationary state, only aliphatic or benzylic tertiary amides reach a nearly complete conversion of ( E ) isomers into the ( Z ) ones, whereas for esters, primary and secondary amides or aromatic tertiary amides mixtures of ( Z )/( E ) ranging from 7 : 93 to 72 : 28 are observed. Ketones show rather limited photoisomerization. However, ( Z ) ketones may be obtained by the reaction of organometal compounds with an isomerized ( Z ) Weinreb amide.
