Synthesis of seven-membered nitrogen heterocycles through the Ugi multicomponent reaction
, 2017 This paper reviews all the syntheses of 7-membered nitrogen heterocycles that are based on the Ugi multicomponent reaction. Different systems may be obtained in a diversity-oriented manner employing three general strategies: i) intramolecular Ugi ...

Diastereoselective Ugi reaction for the synthesis of unnatural amino esters
, 2012 Multicomponent Reactions (MCR) are useful reactions to obtain complex products by the simple mixture of 3 or more reactants. The classic Ugi reaction (4-UCR) involves a mixture of an amine, aldehyde, isocyanide and a carboxylic acid, giving peptoides as ...

Application of the Ugi Reaction for the One-Pot Synthesis of Uracil Polyoxin C Analogues
, 2016 A simple, two-step synthesis of amide derivatives of uracil polyoxin C (UPOC) methyl ester using the Ugi reaction is described. The four components employed in the Ugi reaction are 2′,3′-isopropylidine-protected uridine-5′-aldehyde, 2,4 ...

Insight into the mechanisms of the multicomponent Ugi and Ugi-Smiles reactions by ESI-MS(/MS)
, 2014 The mechanisms of the Ugi and Ugi–Smiles reactions were investigated by using finely selected reaction conditions that allowed all of the intermediates to be “fish-out” and characterized by ESI-MS/MS.
