Metal-free anti-Markovnikov hydroalkylation of unactivated alkenes with cyanoacetate has been developed, featuring the use of a dual-component initiator containing an organic photocatalyst and a radical precursor. When combined, the two components can undergo visiblelight-induced single-electron transfer, and serve as a versatile and effective alkyl radical generator.

Decyanation of geminaldinitriles and α-alkoxycarbonyl substituted nitriles promoted by samarium(II) iodide has been efficiently achieved. This method has advantages over the previously known radical route using tin hydride with respect to applicable substrates and the reaction temperature employed. This decyanation could broaden the synthetic applicability of the nitrile derivatives.

A series of simplified alpha-keto heterocycle, trifluoromethyl ketone, and formyl substituted folate analogues lacking the benzoylglutamate subunit were prepared and examined as potential inhibitors of glycinamide ribonucleotide transformylase (GAR Tfase) and aminoimidazole carboxamide transformylase (AICAR Tfase).
