A AuIII-catalyzed synthesis of α-halomethyl ketones from terminal alkynes was developed. This approach features excellent functional group compatibility and good yields for both aromatic and aliphatic terminal alkynes. The resulting α-halomethyl ketones were used to prepare heterocyclic indolizine structures. The plausible mechanism of the one-pot reaction is proposed.

supporting information; experimental part, p. 432 - 434 (2012/06/01)
A simple protocol for the α-monochlorination of ketones and 1,3-dicarbonyl compounds utilizing NH4Cl as a source of chlorine and Oxone as an oxidant in methanol without catalyst is presented. The reaction proceeds at ambient temperature in yields ranging from moderate to excellent.
