Development, synthetic scope, and mechanistic studies of the palladium-catalyzed cycloisomerization of functionalized 1, 6-dienes in the presence of silane

A catalytic reductive cleavage of C(sp(2))- and C(sp(3))-SMe bonds under ligandless conditions is presented. The method is characterized by its wide scope and high chemoselectivity profile including challenging substrate combinations, allowing the design of orthogonal and site-selectivity approaches.

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
