Abstract
(Chemical Equation Presented) Highly functionalized and conformationally constrained depsipeptides based on a dihydropyridin-2-one core are prepared by the combination of a four- and a three-component reaction. The synthesis combines a one-pot Horner-Wadsworth-Emmons/cyclocondensation sequence leading to isonitrile-functionalized DHP-2-ones with an isonitrile-based Passerini multicomponent reaction (MCR). Substituents could be independently varied at six different positions. The two MCRs could also be performed as a one-pot procedure, simplifying the protocol and leading to a new and highly variable six-component process. © 2007 American Chemical Society.
