Recently, we have developed a novel amine–Pd(OAc) 2 co-catalyzed direct Saegusa oxidation reaction of unmodified β-aryl aldehydes to α,β-unsaturated aldehydes (Scheme 1, eqn (1)). 13 In our continuing efforts aimed at developing more efficient synthetic tools toward the highly valuable building blocks, we questioned whether it might be possible to merge the widely used Heck reaction with the direct Saegusa oxidation process to create a new one-pot approach to these ...
