β-Keto esters are one of the most widely used building blocks in organic chemistry and undergo various types of substitution reactions. Particularly, β-keto esters undergo C-C bond formation reactions in the reaction with carbon elecrophiles. However, electrophilic addition reactions of β-keto esters are rare in the literature. More interestingly, transition-metal-catalyzed nucleophilic addition reactions of β-keto esters to olefins have been well reported in which β-keto esters usually act as a nucleophile to afford cyclic compounds. Recently, we have discovered a novel synthetic method for the synthesis of indene derivatives in good yields. Ph3PAuCl/AgOTf catalyzed effectively the intramolecular addition reactions of alkenes to β-keto esters to provide a variety of substituted indenes in moderate to high yields. In addition, this catalytic system was found to be very effective for the carbonyl-ene reaction of allylic β-keto ester derivatives to afford naphthalenes in high yields.
