Proxy Signature with Revocation
, 2016 Proxy signature is a useful cryptographic primitive that allows signing right delegation. In a proxy signature scheme, an original signer can delegate his/her signing right to a proxy signer or a group of proxy signers who can then sign documents on behalf of the original signer.

Synthetic Strategies for the Construction of Cyclobutane‐Fused Heterocycles
European Journal of Organic Chemistry, EarlyView.Cyclobutane‐fused heterocycles are important motifs commonly present in bioactive compounds, recognized for their rigid 3D structures that confer unique properties. However, synthesizing these compounds remains challenging. This review discusses current methods for their synthesis, such as photochemical, metal‐catalyzed, and Lewis acid‐mediated [2 + 2]

Selective N‐Functionalization of Pyrazoles
European Journal of Organic Chemistry, EarlyView.This review traces the evolution of regioselective N‐functionalization strategies for pyrazoles, a key class of nitrogen heterocycles widely used in medicinal chemistry. Due to rapid tautomerism, N‐functionalization often lacks selectivity, leading to poor and unpredictable regioisomeric outcomes.

European Journal of Organic Chemistry, EarlyView.A practical strategy for synthesizing β‐ and γ‐carbolinones from indole‐based Ugi 4‐CR adducts through an intramolecular radical cyclization using Fe(III)–H species is presented. This approach enables the efficient synthesis of spiro‐carbolinones under mild reaction conditions and demonstrates the effectiveness of secondary radicals in both cyclization

Counterion Effects in Decatungstate Photocatalysis
European Journal of Organic Chemistry, EarlyView.Decatungstate photocatalysis is often discussed from an anion‐centered perspective, treating the counterion as a passive charge‐balancing species. This review highlights that counterion identity can instead profoundly influence catalyst solubility, ion pairing, aggregation, stability, substrate accessibility, and catalytic performance.
