Unstabilized tertiary organolithium intermediates are conveniently generated by reductivedecyanation of nitriles, and these reagents and their derived cuprates couple in useful yields with carbon‐ centered electrophiles (see example). Chiral tertiary organolithium and organocuprate derivatives of substituted cis‐perhydroazulenes and cis‐perhydropentalenes react with electrophiles with high diastereoselectivity
