The gold‐catalysed double functionalisation of indoles is presented. Enynones are used to annulate indoles via a double sodium tetrachloroaurate‐catalysed process involving a mixture of CH activation and alkyne activation modes of promotion. Good yields for the formation of medicinally relevant [6,5,7]‐tricyclic indoles are realised.

The allylamine derivatives are a new class of syntheticantifungalagents inhibiting fungal squalene epoxidase. A new subclass, which features an acetylene group conjugated with the allylamine double bond, is characterized by enhanced antifungal activity, especially on oral treatment of guinea pig dermatophytoses. Increased branching of the alkyl group next to the triple bond led to the tert-butylacetylene

A study of the stereoselective halogenation of 6,6-dimethyl-1-hepten-4-yn-3-ol (1) using a series of halogenating agents is described. Of the many agents investigated, boron trichloride is the most successful reagent for stereoselective halogenation (E:Z=9:1max). The resulting (E)-1-halo-6,6-dimethyl-2-hepten-4-yne (2), a keyintermediate for terbinafine, an antifungal agent, is obtained in good yield
