An efficient method for visible-light-induced perfluoroalkylaion of quinolin-4-ol has been reported. In the presence of t-BuONa and perfluoroalkyl iodide, quinolin-4-ol underwent CH perfluoroalkylation under the irradiation of green light. Mechanistic studies demonstrated that visible-light promoted intermolecular charge transfer within the transient electron donor-acceptor complex in the absence of
A derivative, which is useful as a ret kinase inhibitor is described herein. The described invention also includes methods of using the same in the treatment of diseases mediated by inappropriate ret kinase activity.

propenylation reaction of allylic carbonates with 4‐hydroxypyridine derivatives. The process efficiently provides 4‐pyridone derivatives with high stereoselectivities under mild conditions. The products could constitute valuable building blocks for the synthesis of natural products and other bioactive molecules. Preliminary mechanistic studies indicated that a tandemallylic substitution/isomerization
