Minisci-type alkylation of electron-deficient heteroarenes has been a pivotal technique for medicinal chemists in the synthesis of drug-like molecules. However, such transformations usually require harsh conditions (e.g., strong acids, stoichiometric amount of oxidants, elevated temperatures, etc.). Herein, by utilizing photoredoxcatalysis, a highly-selective alkylation method using heteroaryl sulfones
Phosphatidylinositol (PI) 3-kinase inhibitor compounds, their pharmaceutically acceptable salts, and prodrugs thereof; compositions of the new compounds, either alone or in combination with at least one additional therapeutic agent, with a pharmaceutically acceptable carrier; and uses of the new compounds, either alone or in combination with at least one additional therapeutic agent, in the prophylaxis or treatment of diseases characterized by the abnormal activity of growth factors, protein serine/threonine kinases, and phospholipid kinases, including proliferative diseases, inflammatory and obstructive airways diseases, allergic conditions, autoimmune and cardiovascular diseases.
