Synthesis of spirolactones from carbonyls via carboborylation of N‐sulfonylhydrazones with alkoxycarbonylalkylboronic acids

open access: yesAdvanced Synthesis &Catalysis, Accepted Article.
A straightforward synthesis of spirolactones from carbonyls via N‐tosylhydrazones is described. The process consist in the reaction between the N‐tosylhydrazone and ethoxycarbonylethylboronic acid or ethoxycarbonylpropylboronic acid, leading to spiro γ‐butyrolactones or δ‐valerolactones respectively. The transformation takes place by carboborylation of

Pot‐Economical Synthesis of Fluorinated Pyrrolizinone Derivatives

open access: yesAdvanced Synthesis &Catalysis, EarlyView.
Abstract A new family of fluorinated dihydropyrrolizinones has been synthesized starting from fluorinated enamino amides and aliphatic conjugated ketones. The reaction comprises a cross metathesis reaction followed by a tandem cycloaromatization/ enamine hydrolysis/ intramolecular Friedel‐Crafts alkylation sequence.

Synthesis of Polysubstituted Naphthalenes via Metal‐Free Borylative Cyclization of o‐Alkynylstyrenes

open access: yesAdvanced Synthesis &Catalysis, EarlyView.
Abstract A selective, metal‐free method for the synthesis of boron‐functionalized polysubstituted naphthalenes via BCl3‐mediated cyclization of α‐substituted o‐alkynylstyrenes is described. The reaction exhibits broad substrate scope, tolerating various groups such as ethers, sulfides and halogens, and delivers high yields under mild conditions, even ...

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

open access: yesAdvanced 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

Enhanced Oxygen Evolution Reaction Performance of Niobium–Cobalt Oxide Catalysts in Acidic and Alkaline Media

open access: yesAdvanced Sustainable Systems, EarlyView.
The electronic modulation of Nb‐doped Co3O4 catalyst showcases enhanced activity and extended stability for OER in both alkaline (1M KOH) and acidic (0.5M H2SO4) electrolytes. The higher activity emanated from the synergistic effect between the Nb5+ dopant and Co3O4.
