Abstract

AbstractWe report a new iron‐catalyzed I/Zn‐exchange allowing to convert primary 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 aryl iodides) gave various polyfunctional products.magnified image
