Abstract
We report a cascaded oxidative sulfonylation of N-propargylamine via a three-component coupling reaction using DABCO·(SO2)2 (DABSO). 3-Arylsulfonylquinolines were obtained by mixing diazonium tetrafluoroborate, N-propargylamine, and DABSO under argon atmosphere in dichloroethane (DCE) for 1 h. In a radical pathway, DABSO was utilized as the sulfone source and an oxidant in this radical-mediated cascaded reaction.

Abstract
This review aims to provide a comprehensive overview of condensation-based methods for the C-H bond functionalization of amines that feature azomethine ylides as key intermediates. These transformations are typically redox-neutral and share common attributes with classic name reactions such as the Strecker, Mannich, Friedel-Crafts, Pictet-Spengler, and Kabachnik-Fields reaction, while incorporating a redox-isomerization step. This approach provides an ideal platform to rapidly transform simple starting materials into complex amines.

Abstract
A Rh(III)-catalyzed regioselective redox-neutral cascade process of carbenoid functionalization followed by dephosphonylative annulation of benzoic acids with α-diazo-β-keto phosphonate has been realized, which led to the direct synthesis of a privileged 3-substituted isocoumarin scaffold. To the best of our knowledge, this is the first report of a complete redox neutral method to synthesize isocoumarins using C-H functionalization strategy. In the catalytic cycle of this reaction, there are two possible pathways for the C-C coupling between ortho-positioned carbon atom of benzoic acid and the diazo carbon atom: (i) concerted 1,2-aryl shift and (ii) stepwise metal-carbene formation followed by migratory insertion. DFT study has predicted that the concerted pathway has lower activation energy as compared to the stepwise pathway by 1.5 kcal/mol.

Abstract
Amines such as 1,2,3,4-tetrahydroisoquinoline undergo redox-neutral annulations with ortho-(nitromethyl)benzaldehyde. Benzoic acid acts as a promoter in these reactions, which involve concurrent amine α-C-H bond and N-H bond functionalization. Subsequent removal of the nitro group provides access to tetrahydroprotoberberines not accessible via typical redox-annulations. Also reported are decarboxylative annulations of ortho-(nitromethyl)benzaldehyde with proline and pipecolic acid.

Abstract
Amines such as 1,2,3,4-tetrahydroisoquinoline undergo redox-neutral annulations with ortho-cyanomethylbenzaldehydes. These amine α-C-H bond functionalization reactions are promoted by acetic acid. The resulting β-aminonitriles can be converted to the corresponding β-aminoalcohols in diastereoselective fashion.

Abstract
α-Ketoamides undergo redox-annulations with cyclic secondary amines, such as 1,2,3,4-tetrahydroisoquinoline, pyrrolidine, piperidine, and morpholine. Catalytic amounts of benzoic acid significantly accelerate these transformations. This approach provides polycyclic imidazolidinone derivatives in typically good yields.

Abstract
Amines such as 1,2,3,4-tetrahydroisoquinoline undergo redox-neutral annulations with 2-alkylquinoline-3-carbaldehydes as well as the corresponding 4-alkyl isomers and pyridine analogues. These processes involve dual C-H bond functionalization. Acetic acid is used as a cosolvent and acts as the sole promoter of these transformations.

Abstract
Reaction of thioamides (e.g., II) with benzynes generated by the hexadehydro-Diels-Alder (HDDA) cycloisomerization (e.g., I) produces dihydrobenzothiazines (e.g., III). It is postulated that the reaction proceeds via benzothietene (cf. IV) and o-thiolatoaryliminium (cf. V) intermediates and that the latter undergoes intramolecular 1,3-hydrogen atom migration to produce the penultimate isomeric iminium zwitterions VI.

Cyclic amines such as pyrrolidine and piperidine are known to undergo condensations with aldehydes to furnish pyrrole and pyridine derivatives, respectively. A combined experimental and computational study provides detailed insights into the mechanism of pyrrole formation. A number of reactive intermediates (e.g., azomethine ylides, conjugated azomethine ylides, enamines) were intercepted, outlining strategies for circumventing aromatization as a valuable pathway for amine C-H functionalization.

Abstract
We describe a general method to synthesize the iminium tetrahydrothiophene embedded in the dimeric Nuphar alkaloids. In contrast to prior studies, the sulfur atom of the thiaspirane pharmacophore is shown to be electrophilic. This α-thioether reacts with thiophenol or glutathione at ambient temperature to cleave the C-S bond and form a disulfide. Rates of conversion are proportional to the corresponding ammonium ion pK a and exhibit half-lives less than 5 h at a 5 mM concentration of thiol. A simple thiophane analogue of the Nuphar dimers causes apoptosis at single-digit micromolar concentration and labels reactive cysteines at similar levels as the unsaturated iminium "warhead". Our experiments combined with prior observations suggest the sulfur of the Nuphar dimers can react as an electrophile in cellular environments and that sulfur-triggered retrodimerization can occur in the cell.

Abstract
Cyclic amines such as pyrrolidine and 1,2,3,4-tetrahydroisoquinoline undergo redox-annulations with α,β-unsaturated aldehydes and ketones. Carboxylic acid promoted generation of a conjugated azomethine ylide is followed by 6π-electrocylization, and, in some cases, tautomerization. The resulting ring-fused pyrrolines are readily oxidized to the corresponding pyrroles or reduced to pyrrolidines.

Abstract
![]()
Cyclic amines such as 1,2,3,4-tetrahydroisoquinoline
undergo regiodivergent
annulation reactions with 4-nitrobutyraldehydes. These redox-neutral
transformations enable the asymmetric synthesis of highly substituted
polycyclic ring systems in just two steps from commercial materials.
The utility of this process is illustrated in a rapid synthesis of
(−)-protoemetinol. Computational studies provide mechanistic
insights and implicate the elimination of acetic acid from an ammonium
nitronate intermediate as the rate-determining step.

Abstract
Cyclic amines such as pyrrolidine undergo redox-annulations with 2-formylaryl malonates. Concurrent oxidative amine α-CH bond functionalization and reductive N-alkylation render this transformation redox-neutral. This redox-Mannich process provides regioisomers of classic Reinhoudt reaction products as an entry to the tetrahydroprotoberberine core, enabling the synthesis of (±)-thalictricavine and its epimer. An unusually mild amine-promoted dealkoxycarbonylation was discovered in the course of these studies.

Abstract
A long-known class of cyclic amine/aldehyde condensation reactions was reinvestigated. Benzoic acid was found to efficiently promote condensations of amines such as piperidine or 1,2,3,4-tetrahydroisoquinoline with aromatic aldehydes, resulting in amine β-functionalization and aromatization. These redox-neutral transformations provide 3,5-dialkylpyridines and 4-alkylisoquinolines in moderate to good yields, following short reaction times under microwave conditions.

Abstract
![]()
Redox-neutral
methods for the functionalization of amine α-C–H
bonds are inherently efficient because they avoid external oxidants
and reductants and often do not generate unwanted byproducts. However,
most of the current methods for amine α-C–H bond functionalization
are oxidative in nature. While the most efficient variants utilize
atmospheric oxygen as the terminal oxidant, many such transformations
require the use of expensive or toxic oxidants, often coupled with
the need for transition metal catalysts. Redox-neutral amine
α-functionalizations that involve intramolecular
hydride transfer steps provide viable alternatives to certain oxidative
reactions. These processes have been known for some time and are particularly
well suited for tertiary amine substrates. A mechanistically distinct
strategy for secondary amines has emerged only recently, despite sharing
common features with a range of classic organic transformations. Among
those are such widely used reactions as the Strecker, Mannich, Pictet–Spengler,
and Kabachnik–Fields reactions, Friedel–Crafts alkylations,
and iminium alkynylations. In these classic processes, condensation
of a secondary amine with an aldehyde (or a ketone) typically leads
to the formation of an intermediate iminium ion, which is subsequently
attacked by a nucleophile. The corresponding redox-versions of these
transformations utilize identical starting materials but incorporate
an isomerization step that enables α-C–H bond functionalization.
Intramolecular versions of these reactions include redox-neutral amine α-amination,
α-oxygenation, and α-sulfenylation. In all cases, a reductive
N-alkylation is effectively combined with an oxidative α-functionalization,
generating water as the only byproduct. Reactions are promoted
by simple carboxylic acids and in some cases
require no additives. Azomethine ylides, dipolar species whose usage
is predominantly in [3 + 2] cycloadditions and other pericyclic processes,
have been identified as common intermediates. Extension of this chemistry
to amine α,β-difunctionalization has been shown to be
possible by way of converting the intermediate azomethine ylides into
transient enamines. This Account details the evolution of this
general strategy and
the progress made to date. Further included is a discussion of related
decarboxylative reactions and transformations that result in the redox-neutral
aromatization of (partially) saturated cyclic amines. These processes
also involve azomethine ylides, reactive intermediates that appear
to be far more prevalent in condensation chemistry of amines and carbonyl
compounds than previously considered. In contrast, as exemplified
by some redox transformations that have been studied in greater detail,
iminium ions are not necessarily involved in all amine/aldehyde condensation
reactions.
