Iron-Catalyzed Annulation of 1,2-Diamines and Diazodicarbonyls for Diverse and Polyfunctionalized Quinoxalines, Pyrazines, and Benzoquinoxalines in Water
Pandit, Rameshwar Prasad,Kim, Sung Hong,Lee, Yong Rok
, p. 3586 - 3599 (2016)
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

Metal carbenes, derived from the decomposition of diazo compounds, are valued for their capacity to perform a variety of transformations. A unique class of acyclic, bis-diazo compounds, the donor-acceptor-acceptor 1,3-bisdiazo compounds, are described her
Synthesis of 2-aminofurans and 2-unsubstituted furans via carbenoid-mediated [3 + 2] cycloaddition

experimental part, p. 3133 - 3135 (2012/05/04)
An efficient dual synthetic manifold for 2-aminofurans and 2-unsubstituted furans has been developed. The carbenoid-mediated [3 + 2] cycloaddition of copper carbenoids with enamines provides 2-amino-2,3-dihydrofurans which serve as common intermediates for both 2-aminofurans and 2-unsubstituted furans.

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
