By employing a radical process, enolizable aldehydes were utilized as substrates in the three-component radical homo-Mannich reaction for the streamlined synthesis of γ-amino-carbonyl compounds. The electrophilic radicals were generated from thiols HSCHR1C(O)R2 (R1 = H, Me; R2 = Me, EtO, PhCH2O, 1-adamantyl, Et2N, etc.) via the desulfurization process facilitated by visible-light, and then added to the electron-rich double bonds of enamines, formed in-situ from aldehydes or ketones R3CH2C(O)R4 [R3 = H, Et, MeSCH2, Ph, PhCH2, etc., R4 = H; R3 = H, R4 = Ph, 3-FC6H4, etc.; R3R4 = (CH2)5, CH2CHPhCH2CH2, CH2N(CH2Ph)CH2CH2, etc.] and amines R5NHR6 [R5 = Me, R6 = H2C:CHCH2, PhCH2, cyclohexyl, etc.; R5 = PhCH2, R6 = PhCH2, EtO2CCH2, etc.; R5R6 = (CH2)4, CHPh(CH2)3, etc.] to provide the products I in a single step. The broad scope, mild conditions, high functional group tolerance, and modularity of this metal-free approach for the synthesis of complex tertiary amine scaffolds will likely be of great utility to chemists in both academia and industry.
