The Stephenson s work undoubtedly stimulates a rapid development of visible-light-driven C(sp )-H bond functionalization of tertiary amines. Soon afterward, numerous nucleophiles were employed under the principle of iminium ions chemistry by visible-light photoredox catalysis (Scheme 3.4). The oxidative Mannich reaction of Af-Aryl tetrahydroisoquinoUnes with ketones [17] and enol silanes [18] were developed by Rueping and Xia, respectively. As a follow-up work. Rueping et al. [19] reported an efiicient alkynylation of a-C(sp )-H bond... [Pg.73]

As a recent progress in the radical cyclization methodology, Liu applied visible-light photoredox catalysis (Scheme 43) [66] in the presence of /cc-Ir(ppy)3 complex as a potent photoredox catalyst, blue LED irradiation ( =450nm) to a mixture of a-bromo ester 95 and styrene derivative 96 resulted in clean formation of y-lactone 97. [Pg.272]

One of the most important routes to diverse 3,3-disubstituted oxindoles is the tandem radical cyclization of JV-arylacrylamides [39]. Visible-light photoredox catalysis has proved to be a powerful tool in providing reactive radical intermediates. The development of photocatalytic radical cyclizations ofJV-arylacrylamides... [Pg.422]

At the same time. Rueping and coworkers reported a similar functionalization of peptides and glycine esters through a combination of visible-light photoredox catalysis and Lewis acid catalysis (Eqs. (13.21) and (13.22)) [63]. The addition of the Lewis acid Zn(OAc)2 was essential for C-H arylation due to its capacity to activate the electrophilic imine intermediate. [Pg.431]
