Abstract

Multi-component coupling reactions (MCRs) are a versatile means of obtaining complex molecules in a single step. 1 These reactions are extremely atom-efficient and often high-yielding. The Passerini MCR couples an aldehyde, a carboxylic acid and an isocyanide to yield a product containing a new stereogenic centre and both ester and amide functionalities (step a, Scheme 1). 2 An interesting variation of the Passerini three-component reaction has been reported, where the initial ...
