The use of the coinage metals copper, silver, and gold enables an efficient and stereoselective assembly of bioactive heterocycles via allenic intermediates. Whereas copper is mediating or catalyzing the synthesis of functionalized allenes by SN2′-

The gold-catalyzed endo-cycloisomerization of allenes bearing nucleophilic substituents in the α- or β-position opens up a versatile access to various five- and six-membered heterocycles. Key features of these transformations are the high reactivit

The title compound, C12H15ClF3NO4, is a side product in a synthesis of novel furanomycin derivatives. The stereochemistry at the bicyclic core is consistent with a halolactonization step. However, racemization also occurred via an unknown mechanism
