Dirhodium tetrakis((S)-N-(dodecylbenzenesulfonyl)prolinate) (Rh-2(S-DOSP)(4)) catalyzed reaction of 1,2-dihydronaphthalenes with an excess of methyl vinyldiazoacetates results in a formal double C-H activation, generating four new stereogenic centers with very high stereoselectivity. The mechanism of the C-H activation is complex, involving a combined C-H activation/Cope rearrangement followed by a retro-Cope rearrangement.
