Synergistic Visible Light Nanophotocatalysis and Asymmetric Organocatalysis for the Stereoselective α‐Alkylation of Aldehydes

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.

Regio‐, Stereoselective, Aerobic and Metal‐Free Synthesis of Z‐Vinyl Sulfides: One‐Pot Hydroiodination of Internal Alkynes and in situ Sulfenylations

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

Chemoselective Synthesis of α‐Chloro and α,α‐Dichloro Acetamidines via the Carbenoids Addition to Inherently Low Electrophilic Carbodiimides

Advanced Synthesis &Catalysis, EarlyView.
Carbodiimides act as competent electrophilic synthons for the chemoselective addition of lithium mono‐ and di‐halocarbenoids. The transformation is provided through a single synthetic operation—hitherto elusive—halogenated acetamidines. Interestingly, the constitutively tamed electrophilicity of the starting materials is effectively counterbalanced by ...
