The widespread adoption of high-throughput experimentation (HTE) has transformed asymmetric catalysis by enabling the parallel execution of numerous reactions to systematically explore chemical space instead of relying on isolated trial and error. Currently, the overall efficiency of this process is limited by analytical readouts rather than reaction setups. Specifically, the rapid and reliable determination of enantiomeric excess (ee) from complex crude mixtures remains a primary bottleneck. To address this bottleneck, recent advancements in chiral analytical methodologies offer solutions through either serial analysis to shorten individual measurement times and increase information density or parallel analysis to multiplex signals for formats using microplates. These techniques span chromatography, spectroscopy, mass spectrometry, and nuclear magnetic resonance. Key factors in applying these methods include their compatibility with multiple substrates, robustness against matrix interference, and the ability to balance speed with accuracy, which allow for earlier evaluation of substrate generality and minimizes bias towards a single substrate. This proactive approach ultimately generates high-dimensional datasets that effectively guide the optimization of catalysts and reaction conditions toward universally applicable asymmetric transformations. In this review, we summarize these recent advancements in high-throughput chiral analytical methodologies and highlight their profound impact on accelerating discovery in the field of asymmetric catalysis.

Harziandione is a diterpenoid natural product featuring a 6/5/7/4 tetracyclic core with four contiguous stereocenters, two of which are quaternary. Herein, we report the rapid assembly of its tetracyclic framework in just nine steps from commercially available cyclopentenone, strategically enabled by gold(I) catalysis. The strained bicyclo[5.2.0]nonene motif was assembled via a gold(I)-catalyzed formal [2 + 2] cycloaddition, while the congested bridged [3.2.1] ring system was constructed through a gold(I)-catalyzed Conia-ene reaction. Subsequently, the pivotal C11 enone was installed using a sequence featuring olefin dihydroxylation and Babler-Dauben oxidation as key transformations.

Herein, we report a nickel-catalyzed regioselective dihydrosilylation of allenes to access 1,3-bis(silane)s bearing two remote silyl groups. Enabled by a commercially available diphosphine ligand (Xantphos), this method proceeds under mild conditions with exclusive regioselectivity, a broad substrate scope, and excellent functional group tolerance. Mechanistic studies support a two-step sequence involving an initial branch-selective hydrosilylation, followed by a linear-selective hydrosilylation of the resulting terminal alkene. 1,3-Bis(silane)s could undergo orthogonal transformations into a variety of 1,3-difunctionalized molecules and participate in Pt-catalyzed hydrosilylation polymerization with dialkynes, highlighting the potential of this structural motif in both synthetic chemistry and materials science.

Sulfur hexafluoride (SF6), a chemically inert and stable gas essential to the electric power industry, poses severe environmental risks due to its persistence and high global warming potential. While traditional degradation methods are inefficient, photocatalytic single electron reduction (SER) enables SF6 activation into SF5 radicals, creating opportunities for both degradation and reutilization. The SF5 group, renowned for its strong electron-withdrawing, lipophilic, and bioisosteric features, has great potential in drug discovery, while efficient methods for synthesizing alkyl- or BCP-SF5 motifs remain scarce. As a safe, inexpensive, and atom-economical alternative to conventional SF5 reagents, SF6 serves as an ideal yet underexplored SF5 source. Herein, we present a photocatalytic strategy for the direct synthesis of diverse SF5-containing scaffolds, including ketones, acetals, and bicyclo[1.1.1]pentane derivatives. Derivatization studies demonstrate its synthetic versatility, particularly in accessing alpha-SF5-substituted acetaldehydes. Mechanistic and density functional theory (DFT) studies confirm the single electron reduction of SF6, highlighting a mild, efficient, and broadly applicable route for constructing SF5-functionalized architectures in fluorinated drug development.
