A biomass derived reusable CNO/Fe3O4 nanocatalyst for solvent-free synthesis of benzoxazinones and benzthioxazinones.
An iridium-catalyzed enantioselective coupling reaction of vinyl azides and vinyl benzoxazinones provided access to a new class of enantioenriched N-heterocycles, 3,4-dihydroquinolin-2(1H)-imines.
A Pd-catalyzed ring-expansion reaction of trifluoromethyl benzoxazinones with 2-methylidenetrimethylene carbonate to access 8-membered trifluoromethyl benzoxazocines is reported.
Reported herein is a Rh(III)-catalyzed C–H cross-coupling of benzoxazinones and unactivated styrenes to furnish vinylarene scaffolds. Mechanistic studies, gram-scale experiment and further transformations of this method were also demonstrated.
COAP-Pd-catalyzed asymmetric cascade formal [4 + 1] annulation was developed between racemic vinyl benzoxazinones and N-tosylhydrazone sodium salts, affording trans-2,3-disubstituted indolines in good yields with high stereoselectivity.
