Total Synthesis of a Dimeric Thymol Derivative Isolated from Arnica sachalinensis
Get PDFThe total synthesis of a dimeric thymol derivative (thymarnicol) isolated from Arnica sachalinensis was accomplished in 6 steps. A key biomimetic DielsâAlder dimerization was found to occur at ambient temperature and the final oxidative cyclization occurs when the substrate is exposed to air and visible light. These results indicate that this natural product is likely the result of spontaneous (nonâenzymeâmediated) reactivity
