Attempted Diels-Alder Reactions on Vindoline Derivatives
The Diels-Alder reaction of vindoline and methyl vinyl ketone resulted in a Friedel-Crafts reaction product. In the reaction between the ortho-quinone derivative of vindoline and N-phenylmaleimide, two anomalous products were obtained, a vindoline dimer, and a condensed vindoline derivative.
