Third, we attempted to explore the scope of olefins in the cobaltaelectro-catalysis. Bromo substitution on the acenapthylene was compatible allowing further modification of the product (26). Further, allenes also showcased a similar reactivity to generate the structurally interesting chiral indanes in moderate yields and good enantioselectivity (27-29). Moreover, methylene cyclopropanes (MCPs) were considered as a potential reaction partner. To our delight, MCPs efficiently participated in the transformation, delivering structurally diverse chiral indanes in high enantioselectivities (30-33). Derivatives of biologically relevant apocynin (34), gemfibrozil (35), geraniol (36), and L-menthol (37) were also amenable under this protocol, generating the functionalized products in good yields and selectivities.
