Revisited Mechanistic Implications of the Joullié–Ugi Three-Component Reaction
, 2016 The effect of the solvent on the diastereoselectivity of the Joullié–Ugi three-component reaction (JU-3CR) using an α-substituted five-membered cyclic imine is revisited.

One-pot synthesis of oxoisoindoline-1,2,3-triazole hybrid by a Ugi–click reaction
, 2016 1,2,3-Triazole-3-oxoisoindoline-1-carboxamide system was successfully synthesized by using a combination of Ugi and click reactions. This two-step, one-pot synthesis was started by the reaction of 2-formyl benzoic acid, propargyl amine, and cyclohexyl ...

Acid-Free, Aminoborane-Mediated Ugi-Type Reaction Leading to General Utilization of Secondary Amines
, 2016 A variety of secondary amines have become utilized in the Ugi reaction by using aminoborane 1 as an iminium ion generator. Aldehydes, secondary amines, and isocyanides are coupled in the presence of 1 at room temperature, giving the corresponding α-amino
