Synthesis of isoxazoles by hypervalent iodine-induced cycloaddition of nitrile oxides to alkynes.
Chemical Communications, 2011 Treatment of oximes with hypervalent iodine leads to substituted isoxazoles via rapid formation of nitrile oxides. Reaction with terminal alkynes led to a series of 3,5-disubstituted isoxazoles with complete regioselectivity and high yield, in a ...

Advanced Synthesis &Catalysis, EarlyView.An unprecedent dual catalytic nanophotocatalytic and asymmetric organocatalytic system for the α‐functionalization of aldehydes is developed using carbon nanodots as photosensitizers. The optimized methodology yields the alkylated products with up to 94% yield and up to 98:2 e.r., evidencing the possible recycling of the nanocatalysts.

Advanced Synthesis &Catalysis, EarlyView.Abstract A novel, metal‐free, air‐ and moisture‐compatible one‐pot tandem protocol for the regio‐ and stereoselective synthesis of Z‐vinyl sulfides (achieving yields up to 99%), is reported. This straightforward and efficient process combines the selective hydroiodination of internal alkynes, promoted by the eutectic mixture choline iodide (ChI)/p‐TsOH
