The intramolecular hydroacylation of 1,2-disubstituted alkenes was considered to be a challenging task due to the side reactions resulted from the lack of additional substituent at 1-position and the low activity caused by the steric hindrance of substituent at 2-position, and an asymmetric version has not been considered possible due to problems associated with the racemization of the products. We have partially solved these problems. Catalyzed by an activated diphosphine-Rh complex and reacted in a selected dihalogenated solvent, the intramolecular hydroacylation of o-(2-arylvinyl)benzaldehydes provided the corresponding 2-aryl-1-indanones in high yields, and its asymmetric variant using o-(2-alkylvinyl)benzaldehydes afforded chiral 2-alkyl-1-indanones in high yields and with moderate enantioselectivities.
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
CYCLOPALLADATED IMINES IN SYNTHESIS: THE PREPARATION OF UNSYMMETRICAL STILBENES AND 3-ARYLISOQUINOLONES
Girling, I. R.,Widdowson, D. A.

A series of cyclopalladated t-butylimines of aromatic aldehydes were reacted with styrene to give o-formylstilbenes in high yield.The N-methylimines of these were converted to 3-aryl-N-methyl-isoquinolones by oxidation with mercuric acetate.
