either twisted-amides or heteroaryl halides with alkylhalides, enabled by ball-milling, is herein described. The operationally simple nickel-catalyzed process has no requirement for inert atmosphere or dry solvents and delivers the corresponding acylated or heteroarylated products across a broad range of substrates. Key to negating the necessity of inert reaction conditions is the mechanical activation

or tailored secondary alkyl iodides into the corresponding alkylzinc iodides. In the presence of a remote double bond at position 5, diastereoselective ring closures are observed. Quenching of these zinc reagents, after transmetalation to copper species (with CuCN ⋅ 2LiCl) or under Pd-catalysis, with typical electrophiles (allyl bromides, acid chlorides or aryliodides) gave various polyfunctional
