An efficient Cu(ii)-catalyzed, C-H alkylation of BODIPY with a variety of alkyl diacyl peroxides has been developed for the first time, providing a late-stage and straightforward method for controllable synthesis of monoalkylated and dialkylated BODIPYs via a radical process that otherwise is difficult to obtain by literature methods. This chemo- and site-selective transformation will allow for the introduction of a variety of functionalities on the BODIPY core for highly versatile tethering to receptors and to other molecules of interest.

We have disclosed a new radical-mediated decarboxylative C(sp3)?N cross-coupling of diacyl peroxides with nitrogen nucleophiles. The primary and secondary alkyl radicals derived from corresponding diacyl peroxides were generated by copper catalysis or by merging copper catalysis and photoredox catalysis, respectively. Various N-alkyl nitrogen nucleophiles, including indazoles, triazoles, indoles, purine, carbazole, anilines, and sulfonamide, were provided with a broad substrate scope and good functional group tolerance.

Herein, we describe a protocol for alkylation reactions of C(sp3)-H bonds with diacyl peroxides by means of a process involving cross-coupling between an alkyl radical and an α-Aminoalkyl radical. The mild, catalyst-And additive-free conditions make this protocol superior to previously reported C(sp3)-H alkylation strategies. The protocol was applied to 1,2,3,4-Tetrahydroisoquinolines and a tetrahydro-β-carboline derivative and could be carried out on a gram scale, indicating its utility for the alkylation of late-stage synthetic intermediates.
