Abstract

Our program of total synthesis of natural products stimulated our imagination and led us to design various methodologies to build the vinyl chloride function of our targets. The access to vinyl chlorides also offers an entry to the trisubstituted alkenes of pure configuration. Thanks to these methodologies we achieved the synthesis of complex structures such as (+)-oocydin A, a total synthesis that also led us to discover other useful new transformations.
