Abstract

3-lndolcarbaldehyde exibits in Oglialoro condensation different behaviour than 2-furancarbaldehyde and 2- and 3-thiophencarbaldehydes which with substituted acetic acids give 3-(2-furyl), 3-(2-thienyl) and 3-(3-thienyl)-2-substituted acrylic acids. It is noticed that under the same reaction conditions the main product in the reaction of substituted acetic acids with 3-indolcarbaldehyde is not the corresponding 3-(3-indolyl)-2-substituted acrylic acid but the mixed anhydride 2 or 4.
