摘要
The alpha-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. (c) 2005 Elsevier Ltd. All rights reserved.
