Hydroarylation is an effective strategy to rapidly increase the complexity of organic structures by transforming flat alkene moieties into three‐dimensional frameworks. Many strategies have already been developed to achieve the hydroarylation of styrenes, however most of these reports examine the hydroarylation of unpolar, β‐mono‐ or β‐unsubstituted styrenes, while exploring mainly electron‐rich benzene
An electrochemical cinnamyl C—Hamination reaction in the absence of transition metal catalyst and oxidant was reported. The choice of carbonyl sulfamate as nitrogen source is the key to achieve desired chemoselectivity. A series of terminal amine derivatives are prepared using this protocol and the sulfonyl group can be removed with basic hydrolysis. The reaction is suggested to proceed via a continuous

Therapeutic combinations of a phosphoinositide 3-kinase (PI3K) inhibitor, including PI3K inhibitors selective for the γ- and δ-isoforms and selective for both γ- and δ-isoforms (PI3K-γ,δ, PI3K-γ, and PI3K-δ), a Janus kinase-2 (JAK-2) inhibitor, a Bruton's tyrosine kinase (BTK) inhibitor, and/or a B-cell lymphoma-2 (BCL-2) inhibitor are described. In some embodiments, the invention provides therapeutic combinations of a PI3K-δ inhibitor and a BTK inhibitor, a JAK-2 and a BTK inhibitor, and a BCL-2 and BTK inhibitor.
