Schmidt reaction by sulfonium ions is described. General primary, secondary, and tertiary alkyl azides were converted to the corresponding carbonyl or imine compounds without any trace of the activators. This bond scission reaction through 1,2-migration of C–H and C–C bonds was accessible to the one-pot substitution reaction.

This work describes an electrochemically promoted nickel-catalyzed deoxygenative thiolation of alcohols and ketones under mild conditions. Excellent substrate tolerance and good chemical yields can be achieved by graphene/nickel foam electrodes in an undivided cell. Further study to gain mechanistic insight into this electrochemical cross-coupling has been carried out.

proven difficult, the judicious use of HuPhyrin ligand by tuning the bridgelength and other remote non-chiral elements allows for controlling both the degree and sense of asymmetric induction in a systematic manner. This effort leads to successful development of new Co(II)-based catalytic systems that are highly effective for enantiodivergent radical 1,5-C-H amination, producing both enantiomers of the

The present application discloses compounds that are inhibitors of Btk, compounds that are inhibitors of ΡΒΚδ, and compounds that are dual inhibitors of both Btk and PI3Kδ. Also described are methods for synthesizing such inhibitors and methods for using such inhibitors for the treatment of diseases wherein inhibition of Btk and PI3Kδ provides a therapeutic benefit to a patient having the disease.

BTK and PI3Kδ are kinases responsible for B-cell signal transduction, and inhibitors of these enzymes have demonstrated clinical benefit in certain types of lymphoma. Simultaneous inhibition of these pathways could result in more robust responses or overcome resistance as observed in single agent use. We report a series of novel compounds that have low nanomolar potency against both BTK and PI3Kδ as
