The present disclosure relates to bifunctional compounds, which find utility as modulators of Interleukin-1 Receptor-Associated Kinase 4 (IRAK-4); the target protein). In particular, the present disclosure is directed to bifunctional compounds, which contain on one end a Von Hppel-Lindau, cereblon, ligand which binds to the E3 ubiquitin ligase and on the other end a moiety which binds the target protein, such that the target protein is placed in proximity to the ubiquitin ligase to effect degradation (and inhibition) of target protein. The present disclosure exhibits a broad range of pharmacological activities associated with degradation/inhibition of target protein. Diseases or disorders that result from aggregation or accumulation of the target protein are treated or prevented with compounds and compositions of the present disclosure.
An atom economical and metal‐free, one‐pot two‐step asymmetric synthesis of highly valuable 2‐amino‐1‐arylethanols has been established from commercially available starting materials. The effectiveness and scalability of our approach have been demonstrated via the synthesis of the Salbutamol acetate salt, a bronchodilator widely used to treat asthma.
Provided herein is a process for the transfer-hydrogenation of ketone analogs of members of the jervine type of
Veratrum
alkaloids, such as cyclopamine. Also provided herein are novel ruthenium transfer-hydrogenation catalysts.

N-(Substituted-aryl-hydroxyalkylidene)-cycloalkyl carboxamide compositions are disclosed that target molecular elements on sensory nerves. These compounds, preferably administered topically, inhibit the perception of itch and pain and have prolonged duration of action.
