[Au]-catalyzed [3 + 3] cycloaddition reaction of enynones/enynals with azides, which allows the efficient regioselective synthesis of highly fused furo[3,4-d][1,2,3]triazines in good-to-excellent yields under mild conditions, has been developed. The synth

A general and efficient method for the synthesis of cyclic sulfi-nates and sulfinamides based on intra-molecular homolytic substitution (SHi) at the sulfur atom by aryl or alkyl radi-cals is described. Both alkyl and benzo-fused compounds can be accessed di-rectly from easily prepared acyclic pre-cursors. Enantiomerically enriched sulfur-based heterocycles were formed through an SHi process with inversion of configuration at the sulfur atom. Cyclization of prochiral radicals proceeded with varying stereochemical outcomes, depending on the size of the incoming radical. 2-Pyridyl and 2-qui-nolyl radicals led to biaryl compounds, which result from attack onto the ortho position of the arylsulfinate rather than a thiophilic substitution.
