    Abstract: In recent years, successful assay miniaturization has enabled the exploration of synthesis scale reduction in pharmaceutical discovery. Miniaturization of pharmaceutical synthesis and purification allows a reduction in material consumption and shortens timelines, which ultimately reduces the cost per experiment without compromising data quality. Isolating and purifying the compounds of interest is a key step in the library synthesis process. In this manuscript we describe a high-throughput purification workflow in support of microscale (1–5 μmol or 0.5–2 mg) library synthesis. The optimized microscale purification system can routinely purify 384-well reaction plates with an analysis time of 4 min per sample. Instrument optimization, critical parameters such as column loading, delay time calibration, ultrafast pre- and post-purification analysis and library purification examples are provided.

    A compact, practical photoreactor for multi-reaction arrays

    Abstract: The Bristol Myers Squibb Photoreactor (BMS-PR) is a convenient, small-footprint platform that enables routine use of photochemical transformations in a variety of laboratory settings. These photoreactors have been engineered to safely irradiate multiple reaction vessels for array synthesis at various wavelengths and temperatures with a more practical setup than most other commercial photoreactors. The BMS-PR integrates seamlessly with standard laboratory equipment and incorporates a variety of attractive safety features. Herein we describe the BMS-PR460 device for irradiation of reactions at 460 nm using blue light-emitting diodes (LEDs) and highlight its application with photochemical reactions that may be useful in the discovery of novel drug molecules.

    Increasing saturation: development of broadly applicable photocatalytic C sp2 –C sp3 cross-couplings of alkyl trifluoroborates and (hetero)aryl bromides for array synthesis

    Abstract: Visible light photocatalysis has emerged as an enabling technology capable of providing access to architecturally complex molecules. This article describes a systematic investigation of the nickel-mediated photocatalytic cross-coupling of alkyl trifluoroborates and (hetero)aryl bromides aided by high-throughput experimentation (HTE). The results obtained from HTE were utilized to select catalysts, bases and solvents for the production of chemical libraries. Six fourteen-member libraries were generated through couplings with secondary alkyl, primary α-alkoxymethyl, benzyl and secondary α-amino trifluoroborates, demonstrating that the optimized conditions were general, robust and exhibited broad functional group tolerance. The conditions were also successfully adapted for use in a flow reactor, showing the impact micro-scale screening can have in the development of scale-up procedures. These studies enabled the generation of a data-rich reaction guide that provides favorable conditions, as well as alternative conditions that can be used to address issues with substrate solubility or catalyst availability.
