Abstract
Sulfur(VI) Fluoride Exchange (SuFEx) chemistry stands as a well-established method for swiftly constructing complex molecules in a modular fashion. An especially promising segment of this toolbox is reserved for multidimensional SuFEx hubs: three or more substituents pluggable into a singular SVI centre to make 'beyond-linear' clicked constructions. Sulfurimidoyl difluorides (RNSOF2) stand out as the prime example of this, however their preparation from the scarcely available thionyl tetrafluoride (SOF4) limits this chemistry to only a few laboratories with access to this gas. In this work, we identify silver pentafluorooxosulfate (AgOSF5) as a viable SuFEx hub with reactivity equal to SOF4. The AgF2-mediated oxidation of SOCl2 gives rise to the hexacoordinate AgOSF5 adduct, which in contact with primary amines produces the sulfurimidoyl fluorides in high yields. In addition, we have found this workflow to be fully extendable to the trifluoromethyl homologue, AgOSF4CF3, and we propose the use of AgOSF4X salts as a general route to azasulfur SuFEx electrophiles from commercial starting materials.

Abstract
NH-Sulfonimidamides are prepared by copper-catalyzed coupling of primary sulfinamides with secondary amines. Neither a ligand nor an additive is needed, and air is the terminal oxidant. The reactions occur at room temperature, show good functional group tolerance, and lead to products in good yields. A sulfanenitrile is proposed as an intermediate in this oxidative amination.

Abstract
Here, we report the first mechanochemical synthesis of sulfonimidamides. The one-pot, two-step method requires neither a solvent nor inert conditions. In a mixer mill, sulfinamides are rapidly converted to sulfonimidoyl chlorides by oxidative chlorination with N-chlorosuccinimide (NCS). Subsequent substitutions with amines provides a wide range of diversely substituted sulfonimidamides.

Abstract
Sulfonimidoyl halides have previously shown poor stability and selectivity in reaction with organometallic reagents. Here we report the preparation of enantioenriched sulfonimidoyl fluorides and their stereospecific reaction at sulfur with Grignard reagents. Notably the first enantioenriched alkyl sulfonimidoyl fluorides are prepared, including methyl. The nature of the N-group is important to the success of the stereocontrolled sequence to sulfoximines.

Abstract
Sulfur(vi) Fluoride Exchange (SuFEx) chemistry has emerged as a next-generation click reaction, designed to assemble functional molecules quickly and modularly. Here, we report the ex situ generation of trifluoromethanesulfonyl fluoride (CF3SO2F) gas in a two chamber system, and its use as a new SuFEx handle to efficiently synthesize triflates and triflamides. This broadly tolerated protocol lends itself to peptide modification or to telescoping into coupling reactions. Moreover, redesigning the SVI-F connector with a S[double bond, length as m-dash]O → S[double bond, length as m-dash]NR replacement furnished the analogous triflimidoyl fluorides as SuFEx electrophiles, which were engaged in the synthesis of rarely reported triflimidate esters. Notably, experiments showed H2O to be the key towards achieving chemoselective trifluoromethanesulfonation of phenols vs. amine groups, a phenomenon best explained-using ab initio metadynamics simulations-by a hydrogen bonded termolecular transition state for the CF3SO2F triflylation of amines.

Abstract
![]()
A new N-silyl sulfinylamine
reagent allows the
rapid preparation of a broad range of (hetero)aryl, alkenyl, and alkyl
primary sulfinamides, using Grignard, organolithium, or organozinc
reagents to introduce the carbon fragment. Treatment of these primary
sulfinamides with an amine in the presence of a hypervalent iodine
reagent leads directly to NH-sulfonimidamides. This two-step sequence
is straightforward to perform and provides a modular approach to sulfonimidamides,
allowing ready variation of both reaction components, including primary
and secondary amines.

Biginelli-type multicomponent reactions (MCRs) with NH-free sulfonimidamides provide 2,3-dihydro-1,2,6-thiadiazine 1-oxides in high yields. The couplings are performed in a planetary ball mill under solvent-free mechanochemical conditions. Acetic acid or ytterbium triflate are used as catalysts. A representative product was characterized by X-ray single crystal structure analysis revealing molecular details of the highly functionalized three-dimensional heterocycle. Further product modifications lead to additional structural scaffolds.

Abstract
Sulfonimidamides present exciting opportunities as chiral isosteres of sulfonamides, with potential for additional directional interactions. Here, we present the first modular enantioselective synthesis of sulfonimidamides, including the first stereoselective synthesis of enantioenriched sulfonimidoyl fluorides, and studies on their reactivity. A new route to sulfonimidoyl fluorides is presented from solid bench-stable, N-Boc-sulfinamide (Boc=tert-butyloxycarbonyl) salt building blocks. Enantioenriched arylsulfonimidoyl fluorides are shown to be readily racemised by fluoride ions. Conditions are developed, which trap fluoride and enable the stereospecific reaction of sulfonimidoyl fluorides with primary and secondary amines (100 % es, es=enantiospecificity) generating sulfonimidamides with up to 99 % ee. Aryl and alkyl sulfonimidoyl fluoride reagents are suitable for mild late stage functionalisation reactions, exemplified by coupling with a selection of complex amines in marketed drugs.

Abstract
![]()
Sulfoximines
and sulfonimidamides are promising compounds for medicinal
and agrochemistry. As monoaza analogues of sulfones and sulfonamides,
respectively, they combine good physicochemical properties, high stability,
and the ability to build complexity from a three-dimensional core.
However, a lack of quick and efficient methods to prepare these compounds
has hindered their uptake in molecule discovery programmes. Herein,
we describe a unified, one-pot approach to both sulfoximines and sulfonimidamides,
which exploits the high electrophilicity of sulfinyl nitrenes. We
generate these rare reactive intermediates from a novel sulfinylhydroxylamine
(R–O–N=S=O) reagent through an N–O bond fragmentation
process. Combining sulfinyl nitrenes with carbon and nitrogen nucleophiles
enables the synthesis of sulfoximines and sulfonimidamides in a reaction
time of just 15 min. Alkyl, (hetero)aryl, and alkenyl organometallic
reagents can all be used as the first or second component in the reaction,
while primary and secondary amines, and anilines, all react with high
efficiency as the second nucleophile. The tolerance of the reaction
to steric and electronic factors has allowed for the synthesis of
the most diverse set of sulfoximines and sulfonimidamides yet described.
Experimental and computational investigations support the intermediacy
of sulfinyl nitrenes, with nitrene formation proceeding via a transient
triplet intermediate before reaching a planar singlet species.

Abstract
Chiral sulfinyl compounds, sulfoxides, sulfoximines, sulfinamides, and other derivatives, play an important role in asymmetric synthesis as versatile auxiliaries, ligands, and catalysts. They are also recognized as pharmacophores found in already marketed and well-sold drugs (e.g., esomeprazole) and used in drug design. This review is devoted to the modern methods of preparation of sulfinyl derivatives in enantiopure or enantiomerically enriched form. Selected new approaches leading to racemic products for which the asymmetric variant can be developed in the future are mentioned as well.

Abstract
SuFEx reactions, in which an S−F moiety reacts with a silyl‐protected phenol, have been developed as powerful click reactions. In the current paper we open up the potential of SuFEx reactions as enantioselective reactions, analyze the role of Si and outline the mechanism of this reaction. As a result, fast, high‐yielding, “Si‐free” and enantiospecific SuFEx reactions of sulfonimidoyl fluorides have been developed, and their mechanism shown, by both experimental and theoretical methods, to yield chiral products.

Abstract
Sulfonimidamides are obtained in moderate to very good yields from the key intermediates O-benzotriazolyl sulfonimidates, which are formed by reacting aryldiazonium tetrafluoroborates, N-tritylsulfinylamine, and N-hydroxybenzotriazole hydrate in a process mediated by a tertiary amine. The formation of the sulfonimidate proceeds in inexpensive and environmentally benign dimethyl carbonate as the solvent, it does not require anhydrous conditions, and the product yields generally exceed 70 %. The substrate scope is broad, and a wide range of sensitive organic functionalities is well tolerated. The reactions probably proceed via aryl radicals formed from diazonium cations with assistance from both the tertiary amine and the sulfinylamine.

Abstract
The need of a continuous productivity increases in medicinal chemistry laboratories of the pharmaceutical industry motivated the development, over the years, of new software solutions to enable Open-Access in many analytical techniques such as NMR or LC, among others, to characterize and assess the purity of new molecules. These approaches have been widely spread in LC with low resolution MS systems, but similar automated platforms have been rather less explored with high resolution MS. In this work, an improved Automated Open-Access methodology on an UHPLC with DAD coupled to ESI and quadrupole time-of-flight MS system is described. Detailed reports from standard UHPLC-MS runs containing chromatograms and different spectra (MS with different fragmentation) are automatically sent to the chemists. High resolution MS data is typically achieved within ± 1 mDa mass accuracy regardless of sample concentration. Upon training, chemists log-in samples into the system by selecting appropriate methods, being able to interpret the results by themselves in 95% of the cases. The instrument is working unattended, except for a limited number of samples (5%) which require more complex experiments. To the best of our knowledge, this is the first time a completely automated Open-Access LC-HRMS approach has been implemented for medicinal chemists of a pharmaceutical industry.

Abstract
![]()
Sulfondiimines—the double
aza-analogues of sulfones—hold
significant potential as leads in discovery chemistry, yet their application
in this arena has been held back by the scarcity of appropriate synthetic
routes. Existing methods employ sulfides as substrates, and rely on
consecutive imination reactions using the hazardous reagent O-mesitylenesulfonyl hydroxylamine. Here we report a method
for sulfondiimine synthesis that does not begin with a sulfide or
a thiol, and instead employs two Grignard reagents and a bespoke sulfinylamine
(R—N=S=O) reagent as starting materials. Lewis
acid-mediated assembly of these three components provides efficient
access to a series of sulfilimine intermediates. A novel rhodium-catalyzed
imination of these electron-rich sulfilimines then delivers a varied
range of sulfondiimines featuring orthogonal N-functionalization.
Conditions for the selective manipulation of both N-atoms of the sulfondiimines are reported, allowing access to a broad
range of mono- and difunctionalized products. The oxidation of the
sulfilimine intermediates is also described, and provides a complementary
route to sulfoximines.
