- Cascade Process for Direct Transformation of Aldehydes (RCHO) to Nitriles (RCN) Using Inorganic Reagents NH2OH/Na2CO3/SO2F2 in DMSO
-
A simple, mild, and practical process for direct conversion of aldehydes to nitriles was developed feathering a wide substrate scope and great functional group tolerability (52 examples, over 90% yield in most cases) using inorganic reagents (NH2OH/Na2CO3/SO2F2) in DMSO. This method allows for transformations of readily available, inexpensive, and abundant aldehydes to highly valuable nitriles in a pot, atom, and step-economical manner without transition metals. This protocol will serve as a robust tool for the installation of cyano-moieties to complicated molecules.

- Fragment-based discovery of JAK-2 inhibitors
-
Fragment-based hit identification coupled with crystallographically enabled structure-based drug design was used to design potent inhibitors of JAK-2. After two iterations from fragment 1, we were able to increase potency by greater than 500-fold to provide sulfonamide 13, a 78-nM JAK-2 inhibitor.
