In this work, we present a dedicated, high-throughput reaction optimization platform allowing for the rapid evaluation of regiodivergent C–H borylation protocols while minimizing amount starting material required. The workflow was applied to diverse set fragment-like compounds, pharmaceuticals, and agrochemicals, its practicality demonstrated by successfully isolating 36 derivatives bioactive compounds. Leveraging informer library approach, provide comprehensive, side-by-side comparison catalytic methods, revealing insights into strengths, limitations, versatility each protocol. Surprising reactivity patterns, effectiveness ligand-free borylation, utility previously reported directed catalysts outside their expected substrate scope have been noticed. This study highlights potential dedicated platforms expand practical late-stage functionalization pharmaceutical agrochemical research.

Abstract Unnatural amino acids, and their synthesis by the late‐stage functionalization (LSF) of peptides, play a crucial role in areas such as drug design discovery. Historically, LSF biomolecules has predominantly utilized traditional synthetic methodologies that exploit nucleophilic residues, cysteine, lysine or tyrosine. Herein, we present photocatalytic hydroarylation process targeting electrophilic residue dehydroalanine (Dha). This possesses an α , β ‐unsaturated moiety can be combined with various arylthianthrenium salts, both batch flow reactors. Notably, setup proved instrumental for efficient scale‐up, paving way unnatural acids peptides substantial quantities. Our approach, being inherently mild, permits diversification even when they contain sensitive functional groups. The readily available salts facilitate seamless integration Dha‐containing wide range arenes, blueprints, natural products, culminating creation unconventional phenylalanine derivatives. synergistic effect high group tolerance modular characteristic aryl electrophile enables peptide conjugation ligation conditions.

Under mild blue-light irradiation, α-acylated saturated heterocycles undergo a photomediated one-atom ring contraction that extrudes heteroatom from the cyclic core. However, for nitrogenous heterocycles, this powerful skeletal edit has been limited to substrates bearing electron-withdrawing substituents on nitrogen. Moreover, mechanism and wavelength-dependent efficiency of transformation have remained unclear. In work, we increased electron richness nitrogen in azacycles improve light absorption strengthen critical intramolecular hydrogen bonding while enabling direct installation photoreactive handle. As result, broadly expanded substrate scope, including underexplored electron-rich previously unsuccessful now achieved. The significantly improved yields diastereoselectivities facilitated reaction rate, kinetic isotope effect (KIE), quenching studies, addition determination quantum yields. Guided by these propose revised ET/PT contraction, which is additionally corroborated computational characterization lowest-energy excited states through time-dependent DFT. at wavelengths longer than those strongly absorbed was investigated rate measurements, revealed red shift photochemical action plot relative absorbance. elucidated mechanistic photophysical details effectively rationalize empirical observations, additive effects, were poorly understood. Our findings not only demonstrate enhanced synthetic utility shed but may also offer valuable guidance understanding reactivity related systems.
