Iron-Catalyzed Annulation of 1,2-Diamines and Diazodicarbonyls for Diverse and Polyfunctionalized Quinoxalines, Pyrazines, and Benzoquinoxalines in Water

A novel and facile iron-catalyzed tandem annulation of o-phenylenediamines and diazocarbonyls in water for the construction of polyfunctionalized quinoxalines has been developed. The key strategy includes the one-pot domino N?H insertion, cyclization, and

Rhodium(II)- and copper(II)-catalyzed reactions of enol diazoacetates with nitrones: Metal carbene versus lewis acid directed pathways

A complimentary cat.: Copper(II) hexafluoroantimonate catalyzes the formal [3+3] cycloaddition of Lewis acid activated nitrones and vinyl diazoacetates to produce 3,6-dihydro-1,2-oxazines in yields of up to 96 % and diastereoselectivities greater than 25:1 (see scheme). This process compliments the metal carbene pathway that is catalyzed by rhodium(II) species. Copyright
