Abstract

Graphical abstract Ru-catalyzed olefin metathesis has been successfully applied to the synthesis of biscardanol derivatives and cardanol-based porphyrins. Using Hoveyda–Grubbs catalyst ( C627), the reactions were performed with various cardanol derivatives ( 2, 5, 7, and 9) to make novel biscardanol derivatives. With the use of the second-generation Grubbs catalyst ( C848) and Ti(O i Pr) 4, the ring-closing metathesis of cardanol-based porphyrin 11 was carried out to afford cyclic cardanol-based porphyrin derivative 12.
