Abstract: Tandem reactions that involve chemoselective Knoevenagel/Perkin condensation– 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–cinnamoyl hybrids (potent protein tyrosine phosphatase1B inhibitors), cinnamoyl–cinnamic acid hybrids, asymmetric distyrylbenzenes, and biarylstyrenes. Previously reported synthesis require multiple steps and protection/deprotection manipulations
