An efficient methodology to form 4-alkoxy- and 4-aryloxybenzo[d][1,2,3]triazines via an intramolecular heterocyclization of 1-azido-2-[isocyano(p-tosyl)methyl]benzenes under basic conditions has been developed. DFT calculations have been performed to further understand the mechanism of this heterocyclization, which occurs in good to excellent yields with a broad scope. |

Synthesis of anticancer drug bicalutamide promoted by visible light in one step from the corresponding N-arylacrylamide is described. This approach involves a one-pot hydroxysulfonylation reaction via a photocatalytic redox process. The use of Na2Eosin Y as photocatalyst and blue light allows the access to a broad range of α-hydroxysulfonylamides bearing a quaternary center in moderate to good yields with complete regioselectivity via radical process. |

One-Pot (3 + 2) Cycloaddition-Isomerization-Oxidation of 2,2,2-Trifluorodiazoethane and Styryl Derivatives.

A facile access to 5-aryl-3-trifluoromethylpyrazoles has been developed by a one-pot (3 %@2B 2) cycloaddition-isomerization-oxidation sequence employing 2,2,2-trifluorodiazoethane and styryl derivatives. A broad variety of functional groups and good yields are achieved under mild conditions. Additionally, the functionalization of 3-trifluoromethylpyrazoles was studied. DFT calculations of the cycloaddition transition state energies are consistent with the experimentally observed reactivity.
