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 […]
