Synthesis and optimization of substituted furo[2,3-d]-pyrimidin-4-amines and 7H-pyrrolo[2,3-d]pyrimidin-4-amines as ACK1 inhibitors
摘要:
Two classes of ACK1 inhibitors, 4,5,6-trisubstituted furo[2,3-d]pyrimidin4-amines and 4,5,6-trisubstituted 7H-pyrrolo[2,3-d]pyrimidin-4-amines, were discovered and evaluated as ACK1 inhibitors. Further structural refinement led to the identification of potent and selective dithiolane inhibitor 37. (C) 2012 Published by Elsevier Ltd.
Cross‐dehydrogenativecoupling of various terminalalkynes and monohydrosilanes efficiently proceeded in the presence of gold supported on OMS‐2 (Au/OMS‐2) using O2 as a terminal oxidant, affording the corresponding alkynylsilanes in moderate to high yields (see picture). The observed catalysis was truly heterogeneous, and the catalyst could be reused at least ten times without a significant loss of

The development of a scalable asymmetric synthesis of KRAS G12C inhibitor building block 1 is described. The all-carbon quaternary stereocenter was installed enantioselectively via Shi epoxidation, followed by a newly discovered regioselective LaCl3·2LiCl-catalyzed epoxide opening. Subsequent organocatalyzed oxidation provided the requisite ketone, which underwent the final assembly of the heterocyclic
