Abstract
Glycinates, protected enols, and an electrophilic trifluoromethylating reagent were employed to assemble CF3-labeled threonine analogues through a radical addition cascade. To suppress the competing oxidation of the oxyalkyl radical intermediate, various redox catalysts were evaluated and Co(II) exhibited supreme selectivity control with a proper counterion. A series of glycinate and related peptides were thus successfully modified under Co-catalysis. Mechanistic studies revealed that a N-aryl glycinate could be preferentially oxidized by cobalt over the oxyalkyl radical to generate an imine intermediate, and the key to this selectivity could be ascribed to the prechelation of glycinate, as well as a weakly basic carboxylate counterion.

Abstract
![]()
Indole-decorated
glycine derivatives are prepared through an environmentally
benign cross-dehydrogenative coupling between N-aryl
glycine analogues and indoles (yield of ≤81%). Merging heterogeneous
organocatalysis and photocatalysis, C–H functionalization has
been achieved by selective C-2 oxidation of N-aryl
glycines to afford the electrophilic imine followed by Friedel–Crafts
alkylation with indole. The sustainability of the process has been
taken into account in the reaction design through the implementation
of a metal-free recyclable heterogeneous photocatalyst and a green
reaction medium. Scale-up of the benchmark reaction (gram scale, yield
of 69%) and recycling experiments (over seven runs without a loss
of efficiency) have been performed to prove the robustness of the
protocol. Finally, mechanistic studies were conducted employing electron
paramagnetic resonance spectroscopy to unveil the roles of the photocatalyst
and oxygen in the formation of odd-electron species.

Abstract
The possibility to harness aromatic isocyanides as visible-light photocatalysts in the α-amino C(sp3)-H functionalization is herein presented. Actually, the three-component cross-dehydrogenative coupling of aromatic tertiary amines with isocyanides and water leads to amide products under very mild conditions in high yields and with a good substrate scope. While the reaction with aromatic isocyanides proceeds upon direct photoexcitation, aliphatic isocyanides are able to form a photoactive electron-donor-acceptor complex with aromatic amines. Moreover, the use of a catalytic loading of an aromatic isocyanide promotes the oxidative coupling of N-phenyl-1,2,3,4-tetrahydroisoquinoline with an array of different (pro)nucleophiles in good to excellent yields, thus providing the proof-of-concept for the development of a new highly tunable class of organic visible-light photocatalysts.

Abstract
Herein we report an efficient protocol for the C(sp2)-H carbonylation of amino acid derivatives based on an inexpensive cobalt(II) salt catalyst. Carbonylation was accomplished using picolinamide as a traceless directing group, CO (1 atm) as the carbonyl source, and Co(dpm)2 as the catalyst. A broad range of phenylalanine derivatives bearing diverse functional groups were tolerated. Moreover, the method can be successfully applied for the C(sp2)-H carbonylation of short peptides thereby allowing access for peptide late-stage carbonylation.

Abstract
The site-selective functionalization of C-H bonds within a complex molecule remains a challenging task of capital synthetic importance. Herein, an unprecedented Pd-catalyzed C(sp2 )-H alkoxycarbonylation of phenylalanine derivatives and other amines featuring picolinamide as the directing group (DG) is reported. This oxidative coupling is distinguished by its scalability, operational simplicity, and avoids the use of toxic carbon monoxide as the C1 source. Remarkably, the easy cleavage of the DG enables the efficient assembly of isoindolinone compounds. Density Functional Theory calculations support a PdII /PdIV catalytic cycle.

Abstract
An electron donor-acceptor complex-initiated α-cyanation of tertiary amines has been described. The reaction protocol provides a novel method to synthesize various α-amino nitriles under mild conditions. The reaction can proceed smoothly without the presence of photocatalysts and transition metal catalysts, and either oxidants are unnecessary or O2 is the only oxidant. The practicality of this method is showcased not only by the late-stage functionalization of natural alkaloid derivatives and pharmaceutical intermediate, but also by the applicability of a stop-flow microtubing reactor.
