reaction, Sharpless asymmetric dihydroxylation, regioselective iodination, Sonogashira coupling, and rhodium-catalyzed oxidative coupling as key steps. The structure of the keyintermediate for wikstrol A was confirmed via its derivative by single-crystal X-rayanalysis.
The first, concise synthesis of euglobals is accomplished by biomimetic cycloaddition of β-pinene and quinone methides generated by oxidation of grandinol.
