An efficient approach for the organoselenium-catalyzed aza-Wacker reaction of olefinic hydrazones and an oxime to form isoquinolinium imides and an isoquinoline N -oxide is developed. This transformation involves a direct intramolecular C-H amination using hydrazones and an oxime as imine-type nitrogen sources. This work not only provides a new approach for the construction of isoquinoline derivatives, but also expands the scope of nitrogen sources in electrophilic selenium catalysis.
AuI-catalyzed intramolecular cyclization of 2-alkenylphenyl carbonyl compounds: Exploring the oxophilic Lewis acidity of AuI species

A AuI-catalyzed intramolecular cyclization reaction of 2-alkenylphenyl carbonyl compounds to afford a variety of indene, indenol, and indanone ring systems was developed. In this process, AuI serves to activate the carbonyl group of β-keto esters, aldehydes, and ketones, preferentially exhibiting oxophilicity in the presence of C-C multiple bonds. Furthermore, β-keto esters could participate as the electrophilic partner in reactions with carbon nucleophile such as alkenes. Copyright

Golden circle: Two gold-catalyzed oxidative cyclizations of 1,5-enynes using 8-methylquinoline N-oxide are presented (see example). Experimental results indicate that both reactions proceed through prior oxidation of alkyne to form α-carbonyl intermediate
