Tandem reactions that involve chemoselective Knoevenagel/Perkincondensation–decarboxylation–Heck/Suzuki coupling or Heck–aldol sequences have been achieved. This enabled the first concise and efficient synthesis of several important hydroxy‐functionalized compound classes, such as stilbene–cinnamoylhybrids (potent protein tyrosine phosphatase1B inhibitors), cinnamoyl–cinnamic acid hybrids, asymmetric
