Abstract
A new family of chiral chimeric photo-organocatalysts derived from phosphoric acid were synthesized and their spectroscopic and electrochemical properties were investigated. Then, the ability of these photo-activable molecules to catalyse an asymmetric tandem electrophilic β-amination of enecarbamates was evaluated. A new family of chimeric chiral photocatalysts in which a BINOL derived phosphoric acid embeds one or two photosensitizer dyes was prepared. We have demonstrated their ability to catalyse an enantioselective electrophilic amination reaction.![]()

Abstract
A novel and efficient Brønsted acid-promoted hydroamination of hydrazone-tethered olefins has been developed. A variety of pyrazolines have been easily obtained in good to excellent yields with high chemo- and regioselectivity under simple and mild conditions. This method represents a straightforward, facile, and practical approach toward biologically important 5-arylpyrazolines, which are difficult to access by previously reported radical hydroamination of β,γ-unsaturated hydrazones. An efficient, chemo- and regioselective Brønsted acid-promoted hydroamination reaction of hydrazone-tethered olefins towards 5-arylpyrazolines was developed.![]()

Abstract
The late stage functionalization (LSF) of complex biorelevant compounds is a powerful tool to speed up the identification of structure-activity relationships (SARs) and to optimize ADME profiles. To this end, visible-light photocatalysis offers unique opportunities to achieve smooth and clean functionalization of drugs by unlocking site-specific reactivities under generally mild reaction conditions. This review offers a critical assessment of current literature, pointing out the recent developments in the field while emphasizing the expected future progress and potential applications. Along with paragraphs discussing the visible-light photocatalytic synthetic protocols so far available for LSF of drugs and drug candidates, useful and readily accessible synoptic tables of such transformations, divided by functional groups, will be provided, thus enabling a useful, fast, and easy reference to them.

Abstract
![]()
The
Minisci reaction is one of the most valuable methods for directly
functionalizing basic heteroarenes to form carbon–carbon bonds.
Use of prochiral, heteroatom-substituted radicals results in stereocenters
being formed adjacent to the heteroaromatic system, generating motifs
which are valuable in medicinal chemistry and chiral ligand design.
Recently a highly enantioselective and regioselective protocol for
the Minisci reaction was developed, using chiral phosphoric acid catalysis.
However, the precise mechanism by which this process operated and
the origin of selectivity remained unclear, making it challenging
to develop the reaction more generally. Herein we report further experimental
mechanistic studies which feed into detailed DFT calculations that
probe the precise nature of the stereochemistry-determining step.
Computational and experimental evidence together support Curtin–Hammett
control in this reaction, with initial radical addition being quick
and reversible, and enantioselectivity being achieved in the subsequent
slower, irreversible deprotonation. A detailed survey via DFT calculations
assessed a number of different possibilities for selectivity-determining
deprotonation of the radical cation intermediate. Computations point
to a clear preference for an initially unexpected mode of internal
deprotonation enacted by the amide group, which is a crucial structural
feature of the radical precursor, with the assistance of the associated
chiral phosphate. This unconventional stereodetermining step underpins
the high enantioselectivities and regioselectivities observed. The
mechanistic model was further validated by applying it to a test set
of substrates possessing varied structural features.

Abstract
3‐Amino‐substituted saturated nitrogen heterocycles are an important subclass of β‐diamines, appearing in a number of clinical agents. Herein, we report a unified approach to these products based upon the regioselective photoredox‐mediated hydroamination of enecarbamates. The amine coupling partner can encompass diverse amine types under a single set of reaction conditions, including primary alkyl amines, ammonia, aryl and heteroaryl amines, and N−H heterocycles. The method enables the synthesis of a wide range of pharmaceutically relevant building blocks.

Abstract
Highly reactive organometallic species that mediate reductive proton-coupled electron transfer (PCET) reactions are an exciting area for development in catalysis, where a key objective focuses on tuning the reactivity of such species. This work pursues ligand-induced activation of a stable organometallic complex toward PCET reactivity. This is studied via the conversion of a prototypical Cp*FeIII-H species, [FeIII(η5-Cp*)(dppe)H]+ (Cp* = C5Me5-, dppe = 1,2-bis(diphenylphosphino)ethane), to a highly reactive, S = 1/2 ring-protonated endo-Cp*H-Fe relative, triggered by the addition of CO. Our assignment of the latter ring-protonated species contrasts with its previous reported formulation, which instead assigned it as a hypervalent 19-electron hydride, [FeIII(η5-Cp*)(dppe)(CO)H]+. Herein, pulse EPR spectroscopy (1,2H HYSCORE, ENDOR) and X-ray crystallography, with corresponding DFT studies, cement its assignment as the ring-protonated isomer, [FeI(endo-η4-Cp*H)(dppe)(CO)]+. A less sterically shielded and hence more reactive exo-isomer can be generated through oxidation of a stable Fe0(exo-η4-Cp*H)(dppe)(CO) precursor. Both endo- and exo-ring-protonated isomers are calculated to have an exceptionally low bond dissociation free energy (BDFEC-H ≈ 29 kcal mol-1 and 25 kcal mol-1, respectively) cf. BDFEFe-H of 56 kcal mol-1 for [FeIII(η5-Cp*)(dppe)H]+. These weak C-H bonds are shown to undergo proton-coupled electron transfer (PCET) to azobenzene to generate diphenylhydrazine and the corresponding closed-shell [FeII(η5-Cp*)(dppe)CO]+ byproduct.
