Verrucacrylic Acids A and B From a Marine Sponge‐derived Verrucosispora sp. FIM06025
Three new compounds, including two rare cyclopropane‐containing compounds, verrucacrylic acids A and B (1 and 2), and a new amino acid derivative (3), were isolated from Verrucosispora sp. FIM06025, 1 and 2 exhibited weak cytotoxic activity against HL‐60 and T47D. ABSTRACT Verrucosispora sp.

The hidden catalysis of water in the decarboxylative borylation of redox‐active esters with B2cat2 has revealed hypoboric acid catecholate (HAC): an unsymmetric diboron reagent that accelerates the reaction by producing a more reductive boryl chain carrier, upon regioselective radical capture.

Oxidative Generation and Reactivity of the Cyclopropyl Radical From a Martin Silicate
A photoredox strategy employing Martin silicates enables the oxidative generation and controlled capture of cyclopropyl radicals, including the naked one, long considered challenging intermediates. The method affords functionalized cyclopropanes through both Giese‐type additions and dual nickel/photoredox C(sp3)−C(sp2) cross‐couplings.

Nitrooxylation—the installation of nitrate esters (–ONO2) has evolved from classical mixed‐acid protocols to catalytic and mechano‐, flow‐, photo‐, and electrochemical strategies. This review delineates ionic and radical manifolds for C–ONO2 bond formation, emphasizing mechanistic control, selected substrate scope, and selectivity.
