Abstract:
(Chemical Equation Presented) The parent 5H-indazolo[3,2-b]benzo[d]-1,3- oxazine heterocycle as well as a series of novel analogues have been synthesized utilizing two subsequent intramolecular heterocyclizations in one pot. A variety of diversity groups were added to explore the scope of this reaction and to provide a number of new compounds for biological screening. © 2008 American Chemical Society.
