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.
