Aplicability of the Oglialoro condensation in the reaction with 3-indolcarbaldehyde

3-indolcarbaldehyde exhibits in Oglialoro condensation different behaviour than the furan-carbaldehyde and 2- and 3- thiophenecarbaldehydes which with substituted acetic acids give 3-(2-furyl-), 3-(2-thienyl) and 3-(3-thienyl)-2-substituted acrilyc 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 obtained, but the mixed anhydride 2 and 4.
