Based on the strategy of polarity reversal in the generation of free radicals derived from diazo compounds, R1C(=N2)R2[R1 = ethoxycarbonyl, (benzyloxy)carbonyl, N,N-diethylcarbamoyl, etc.; R2 = H, C(O)OMe] photocatalyzed multicomponent reactions (MCRs) of nitrogen aromatic heterocycles, e.g., 4-methylquinoline, alkenes R3CH=CH2 [R3 = methoxymethyl, cyclohexyl, 4-[(furan-2-yl)carbonyloxy]butyl, etc.], and diazo compounds form functionalized derivatives e.g., Et 4-(4-methylquinolin-2-yl)-6-phenylhexanoate in good to high yields and exacting regioselectivities. The carbon radicals generated from the acceptor diazo compounds are electrophilic, and their selective additions with alkenes provide nucleophilic radicals, which enable the further rapid assembly with various heteroarenes. A delicate balance has been achieved between the activation of heteroarenes through protonation and the decomposition of diazo compounds by the same acid. This multicomponent Minisci reaction shows high functional group tolerance, especially in the incorporation of biol. active mols. Detailed mechanistic studies that include photophys. measurements elaborate this radical cascade reaction. Furthermore, this transformation provides new opportunities for versatile reactions of diazo compounds in radical cascade multicomponent coupling reactions.

General procedure: The mixture of isoquinoline 1 (1.3 mmol), terminal alkyne 2 (1.0 mmol), methylperfluoroalk-2-ynoates 3 (1.5 mmol), and CuBr (0.1 mmol) was stirred in toluene (5 mL) under N2. After stirring at room temperature for 24 h, CuBr2 (0.2 mmol), pyridine (1.0 equiv) were added. The mixture was stirred at 100 C under air for an additional 16 h. Then, the reaction was quenched with water and extracted with ethyl acetate (3¡Á5 mL). The combined extracts were washed with brine, dried over anhydrous Na2SO4, and filtered. The filtrate was concentrated. The crude product was purified by flash chromatography on a silica gel (eluent: petroleum ether /ethylacetate) to give pure 5a-5q.
