Using the optimized set of conditions (Table , Entry 6), we next evaluated the scope of the visible-light induced hydroalkylation protocol (Figure ). Hereto, dimethyl maleate 2d was combined with several secondary alkyl iodides and we found that the expected products were obtained in all cases (18-29). Notably, the acid-sensitive acetal function is well tolerated under our optimized conditions (22, 80%). Also iodides of medicinally relevant nitrogen-containing scaffolds, including Boc-protected azetidine, pyrrolidine and piperidine, were competent reaction partners, allowing to isolate the corresponding adducts in good yields (23-26, 57-73%). In a similar vein, oxygen-and sulfur-containing alkyl iodides could be engaged in the reaction protocol (27-29, 40-77%). Next, we employed 1-iodoadamantane as a model for tertiary alkyl iodides and we found that the hydroalkylated product was obtained in very good yield (30, 79%). The presence of a free carboxylic acid slightly reduced the reaction efficiency, however, the targeted compound could still be accessed in synthetically useful quantities (31, 56%).
