Mn(III)-Based Oxidative Free-Radical Cyclizations of Substituted Allyl α-Methyl-β-ketoesters:  Syntheses, DFT Calculations, and Mechanistic Studies

, 2016
The cyclizations of the substituted allyl α-methyl-β-ketoester radicals 11, 14, and 18 were studied by the DFT method at the UB3LYP/6-31G* level; the results show that the cis cyclization is easier than the corresponding trans cyclization, but the ...

Borylcyclopropanes: Synthetic Strategies and Applications

Angewandte Chemie, Volume 138, Issue 37, 7 September 2026.
Borylcyclopropanes (cyclopropanes bearing a boron substituent) sit at the intersection of two privileged frameworks in synthesis. This review provides the first exhaustive survey of their chemistry, spanning metal–carbene, nucleophilic cyclization, radical, hydroboration, and C─H activation routes, and documenting applications in medicinal chemistry ...
