Pd-Catalyzed Site-Selectivep-Hydroxyphenyloxylation of Benzylic α-C(sp3)–H Bonds with 1,4-Benzoquinone
摘要:
A Pd-catalyzed, site-selective p-hydroxypheny-loxylation of benzylic alpha-C(sp(3))-H bonds with 1,4-benzoquinone using thioamide as a directing group is reported. 1,4-Benzoquinone is employed as the p-hydroxyphenyloxy source without extra oxidants. This method exclusively gives site selectivity at alpha-C(sp(3))-H bonds rather than the usual beta-C(sp(3))-H bonds through C-H activation mode. The reactions proceed with high functional group tolerance in yields of 42-93%.

Catalytic Enantioselective α-Fluorination of 2-Acyl Imidazoles via Iridium Complexes
The first highly enantioselective α‐fluorination of 2‐acylimidazoles utilizing iridium catalysis has been accomplished. This transformation features mild conditions and a remarkably broad substrate scope, providing an efficient and highly enantioselective approach to obtain a wide range of fluorine‐containing 2‐acylimidazoles which are found in a variety of bioactive compounds and prodrugs. A large

Nucleophilicaromaticsubstitution (SNAr) reactions of non-activated aryl fluorides with amide enolates are reported. The reaction proceeds under relatively mild reaction conditions. Lactams also participate in the reaction to give 2-arylated lactams. DFT calculations suggest that the reaction proceeds through a concerted SNAr pathway.
