sesquiterpenoid phytoalexin, was developed viaSuzuki-Miyauracoupling. The coupling components were prepared as their corresponding triflates or boronates, starting from the corresponding commercially available ketone and a known keto-ester; the latter is a Diels-Alder product. The reaction was also performed by interchanging the boronate and triflate coupling partners, and the yields were significantly
