[2+1] Cycloaddition of Catalytic Ruthenium Vinyl Carbenes: A Stereoselective Controlled Access to (Z)- and (E)-Vinyl Epoxypyrrolidines Abstract: Aza-alkynals undergo a cyclization reaction with diazo compounds in the presence of catalytic amounts of Cp*RuCl(cod) to afford vinyl […]

Nucleophilic Addition of Amines to Ruthenium Carbenes: ortho-(Alkynyloxy)benzylamine Cyclizations towards 1,3-Benzoxazines

Nucleophilic Addition of Amines to Ruthenium Carbenes: ortho-(Alkynyloxy)benzylamine Cyclizations towards 1,3-Benzoxazines Abstract: A new ruthenium-catalyzed cyclization of ortho-(alkynyloxy)benzylamines to dihydro-1,3-benzoxazines is reported. The cyclization is thought to take place via the vinyl ruthenium carbene intermediates which […]
