Diastereoselective Synthesis of Polysubstituted 2‐Amidino Thiolanes via Cycloaddition of N‐Thioacyl Amidines With Donor–Acceptor Cyclopropanes

Advanced Synthesis &Catalysis, Volume 368, Issue 16, 18 August 2026.
A MgBr2‐catalyzed (3+2) cycloaddition between N‐thioacyl amidines and donor–acceptor cyclopropanes provides rapid access to 2‐amidino‐thiolanes in good yields and with high diastereoselectivities. The method displays broad substrate scope and offers an efficient route to sulfur‐containing amidine scaffolds of potential biological relevance.

Underexplored Catalysts as General Structures: Application of Machine Learning Techniques for Reaction‐Specific Datasets

Angewandte Chemie, Volume 138, Issue 34, 17 August 2026.
Bias‐aware machine learning identified an underexplored imidazolidinone catalyst with broad competitive performance in iminium‐based reactions. Experimental benchmarking shows how data‐driven prioritization can uncover overlooked catalyst scaffolds from sparse and historically biased literature data.

Strain Release of 1‐Azabicyclo[1.1.0]butanes as a Gateway to Highly Functionalized Azetidines: New Strategies and Structural Motifs

Chemistry – A European Journal, Volume 32, Issue 31, 18 August 2026.
Over the past decade, the interest in azetidines has continuously risen, by virtue of their highly appealing pharmaceutical properties. Monocyclic, spirocyclic, and bridged azetidines can be accessed by leveraging 1‐azabicyclo[1.1.0]butanes as precursors.

Stereoselective Higher‐Order [10+4]‐ and [10+6] Cycloadditions Between Two Highly Unsaturated and Ambiphilic π‐Addends

Chemistry – A European Journal, Volume 32, Issue 31, 18 August 2026.
Aminocatalytically generated isobenzofulvenes and 3‐oxidopyridinium betaines act as ambiphilic reaction partners in orbital‐symmetry‐allowed [10+4] cycloadditions or formally symmetry‐forbidden concerted thermal [10+6] cycloadditions. The reaction furnishes three cycloadducts: one [10+4] cycloadduct and two regioisomeric [10+6] cycloadducts.
