The existence of an “isomerization phenomenon” was evidenced, where fast isomerization of 1 into up to …
BiPhePhos is an organophosphorus compound that is used as a ligand in homogeneous catalysis. Classified as a diphosphite, BiPhePhos is derived from three 2,2'-biphenol groups, which constrain its shape in such a way to confer high selectivity to derived catalysts. Originally described by workers at Union Carbide, it has become a standard ligand in hydroformylation. WebSep 18, 2024 · The prenylation of peptides and proteins is an important post-translational modification observed in vivo. We report that the Pd-catalyzed Tsuji-Trost allylation with a Pd/BIPHEPHOS catalyst system allows the allylation of Cys-containing peptides and proteins with complete chemoselectivity and high n/i regioselectivity. In contrast to …
