The Suzuki-Miyaura cross-coupling with chiral γ,γ-disubstituted allylboronates provides nonracemic compounds with quaternary centers with high regioselectivity and enantiospecificity in the presence of RuPhos ligand. The reaction occurs by transmetalation with allyl migration, followed by rapid reductive elimination.
