🚨 Two new C–H bonds borylated – no metals, no catalysts, just light! Excited to share our work, now out in @J_A_C_S: Site-selective β- & γ-C–H borylation of amines, featuring a new tether for elusive β-functionalization. Grateful to Nitish, Tong & Vlad! https://t.co/QoAsIaLJFe
pubs.acs.org
A mild photoinduced transition metal-free method for β- and γ-C(sp3)–H borylation of amines has been developed. This protocol features a regioselective intramolecular hydrogen atom transfer (HAT)...
Please join us in congratulating Sumon, Nitish, & Tong for achieving photoinduced, site-selective β- and γ-borylation of amines using a new, easily installable/ removable radical translocating group, enabling late-stage derivatization. Out now in @J_A_C_S

Direct C–H alkylation could be a very useful strategy for rapidly building molecular diversity, including 3° & 4° carbon centers. Congrats Subham & Gaurav on developing Light-Induced Pd-Catalyzed Allylic C–H Alkylation of Internal Alkenes! out in @J_A_C_S

Check out our latest work on synthesizing allylic ethers, esters, and alkylated motifs! Unlike conventional or direct C–H activation, our approach also enables stereoselective access to allylic sulfones. @J_A_C_S
A multicomponent approach to rapidly build molecular complexity is highly advantageous over other methods. Congrats, Sachin and Nikita, for the development of “General Modular and Convergent Approach to Diversely Functionalized Allylic Systems,” now out in @J_A_C_S @gsachin187
