[reaction: see text]. The asymmetric version of the traditional route for transforming acetylene into alpha-branched carbonyl compounds is now feasible for the first time. The method involves the temporary attachment of camphor to acetylene and gives a remarkably high diastereo- and enantioselectivity.
