The α-effect can be used as an effective means to promote iminiumion 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
