  • Publication number: 20230046065
    Abstract: Palladium-catalyzed C(sp3)—H arylation of aliphatic carboxylic acids, amides and ketones with BNA-encoded aryl iodides in water is disclosed, Furthermore, sequential C—H arylation chemistry enabled the on-DNA synthesis of structurally-diverse scaffolds containing enriched C(sp3) character, chiral centers, cyclopropane, cyclobutane, and heterocycles. That new chemistry permits preparation of a DNA—encoded library (BEL) technology that can dramatically expedite hit identification in drug discovery owing to its ability to perform protein affinity selection with millions or billions of molecules in a single experiment. The sequential functionalization of multiple C—H bonds provides an unique avenue for creating diversity and complexity from simple starting materials. The use of water as solvent, the presence of DMA, and the extremely low concentration of DMA-encoded coupling partners (0.

  • Patent number: 11186563
    Abstract: Chiral acetyl-protected aminoethyl quinoline (APAQ), pyridine and imazoline ligands are disclosed that enable Pd (II)-catalyzed enantioselective arylation or heteroarylation of ubiquitous prochiral ?-methylene C—H bonds of aliphatic amides offers an alternative disconnection for constructing ?-chiral centers. Systematic tuning of the ligand structure reveals that a six-membered instead of a five-membered chelation of these types of ligands with the Pd(II) is important for accelerating the C(sp3)-H activation thereby achieving enantioselectivity for quinoline and pyridine ligands.

  • Patent number: 11133030
    Abstract: A hard disk assembly (HDAs) that include a tuning data memory at least including tuning data regarding the HDA. The HDAs may lack an internal disk controller, but rather may communicate the tuning data and/or other HDA-specific data (e.g., firmware, certification data, etc.) to a reader device comprising a disk controller. In this regard, the reader device may coordinate with the HDA once the tuning data is received to operate the HDA to perform TO commands in response to commands received at the reader device from a host. In turn, upon failure of an HDA, a new HDA may be swapped into place to communicate with the reader device. Because the HDAs may lack onboard disk controllers, the cost and complexity of each HDA may be reduced.
