A general source of dialkoxycarbenes, 2,2-dialkoxy-5,5-dimethyl- Δ3-1,3,4-oxadiazolines, have been successfully employed as coupling partners in CuI-catalyzed cross-coupling reactions with terminal alkynes, which afforded various unsymmetrical propargylic acetals in good yields.

The α-effect can be used as an effective means to promote iminium ion catalysed transformations, providing acyclic scaffolds to aid in catalyst design. A thorough investigation of the structure-activity relationship of the catalyst architecture reveals optimal substituents of a disubstituted carbamate and a secondary alkyl group around a hydrazine scaffold. Molecular modelling investigations provide a mechanistic rationale to the results observed.
