Seven-component reactions by sequential chemoselective Ugi–Mumm/Ugi–Smiles reactions

Chemical Communications, 2010
A seven-component reaction was accomplished by utilizing the different chemoselectivities of the Ugi-Mumm and the Ugi-Smiles reaction. The sequential multicomponent reactions led to highly diverse peptide and glycopeptide like structures.

“Isocyanide-free” Ugi reactions

Organic & Biomolecular Chemistry, 2009
High-yielding Ugi reactions have been carried out with in situ-prepared isocyanides, derived from the reaction of bromide derivatives with silver and potassium cyanide, thus alleviating the burden of the preparation, purification and subsequent use of isocyanides in multicomponent reactions.

Skeletal Diversity by Ugi Four-Component Coupling Reaction and Post-Ugi Reactions

HETEROCYCLES, 2007
Here we report a strategy to alter the skeletal complexity of Ugi four-component coupling reaction products by using allylations followed by ring-closing metathesis. Principal component analysis is also performed for these compounds.
