The use of the coinage metals copper, silver, and gold enables an efficient and stereo-selective assembly of bioactive heterocycles via allenic intermediates. The synthesis of functionalized allenes by SN2'-substitution or SN2'-reduction is mediated or catalyzed by copper, whereas silver and gold are the catalysts of choice for subsequent 5- or 6-endo-cyclizations. Overall, this sequence proceeds with efficient center-to-axis-to-center chirality transfer.
