A diversity-oriented and C2-selective synthesis of difluoroalkyl-substituted heteroarenes from three fragments, N-methoxyazinium salts, difluorocarbene, and electrophilic or radical reagents, is described. The reaction proceeds via the addition of difluorinated phosphorus ylide to in situ methylated heteroarene N-oxides, leading to phosphonium salts, which can undergo further transformations under

[reaction: see text] A strategy for the synthesis of the spirocyclic core of spirolucidine was explored through a modelstudy. The diene 4a was prepared and photolyzed to give the desired [2 + 2] photoadduct 17 containing the correct relative stereochemistry corresponding to spirolucidine.
