Textbook Question

Chapter 21, Problem 1LGP

In “The Chemistry of... Complex Cross Couplings” we showed a Heck reaction used in the synthesis of ecteinascidin 743, a natural compound with anticancer activity isolated from the marine tunicate Ecteinascidia turbinate. Write a mechanism for this reaction, using P d L 2 to represent the palladium catalyst and abbreviating the complicated structures of the ecteinascidin synthetic intermediates as appropriate.
