  α-halo oxime ethers from readily accessible nitronates and nitro compounds via bis(oxy)enamines is reported. A key step of the strategy involves the unprecedented reaction of bis(oxy)enamines with a metal (Co, Zn, Mg, Mn) halide that acts as both a promoter and halide (Br, I, Cl) source. A variety of cyclic and acyclic ethers of α-halo oximes, including previously unavailable trimethylsilyl ethers of α-iodo

  Constitutive activation of NF-κB is associated with proinflammatory diseases and suppression of the NF-κB signaling pathway has been considered as an effective therapeutic strategy in the treatment of various cancers including hepatocellular carcinoma (HCC). Herein, we report the synthesis of 1,2 oxazines and their anticancer potential. The antiproliferative studies presented 3-((4-(1H-benzo[d]imidazol-2-yl)piperidin-1-yl)methyl)-4-phenyl-4,4a,5,6,7,7a-hexahydrocyclopenta [e][1,2]oxazine(3i) as a lead cytotoxic agent against HCC cells. Flow cytometric analysis showed that 3i caused a substantial increase in the subG1 cell population. Annexin-V-FITC-PI staining showed a significant increase in the percentage of apoptotic cells on treatment with 3i. Transfection with p65 siRNA significantly reduced the 3i induced DNA fragmentation indicating that 3i may primarily mediate its proapoptotic effects by abrogating the NF-κB signaling. In addition, treatment of HCC cells with 3i decreased the DNA binding ability of NF-κB and NF-κB-dependent luciferase expression. Taken together, this report introduces 1,2-oxazine that potently targets the NF-κB signaling pathway in HCC cells.

  A novel and efficient four-step procedure for the synthesis of C-3-functionalised 5,6-dihydro-4H-1,2-oxazines from nitroethane is described. It includes preparation of 3-methyl-substituted six-membered cyclic nitronates, 3-(bromomethyl)-substituted 5,6-dihydro-4H-1,2-oxazines as intermediates, and nucleophilic substitution of bromine. Total yields of the target C-3-functionalised oxazines are 15-30%
