Diazo Glutaconimides: an Unexplored Type of Heterocyclic alpha-Diazocarbonyl Compounds Conveniently Evolved into Pyridine-2,6(1H,3H)-diones and Oxazolo[5,4-b]pyridin-5(4H)-ones
A convenient general approach towards 1,4-disubstituted alpha-diazo glutaconimides starting from beta-substituted glutaconic acid anhydrides has been developed. It involves condensation with amines and subsequent diazo transfer reaction. This new class of diazocarbonyl heterocycles has been converted into a series of polysubstituted pyridine-2,6(1H,3H)-diones and oxazolo[5,4-b]pyridin-5(4H)-ones via a Rh-2(esp)(2)-catalyzed XH-insertion reaction and [3+2] cycloaddition with nitriles, respectively.
Reference of 622-75-3, Consequently, the presence of a catalyst will permit a system to reach equilibrium more quickly, but it has no effect on the position of the equilibrium as reflected in the value of its equilibrium constant.I hope my blog about 622-75-3 is helpful to your research.
