Three-component radical homo Mannich reaction [PDF]
Due to the ionic nature of its mechanism, the Mannich reaction can only use non-enolizable aldehydes as substrates. Here, the authors expand the scope of the classical Mannich reaction to enolizable aldehydes by employing a radical process resulting in a

Catalytic Three‐Component Ugi Reaction [PDF]
Perfect atom economy characterizes a novel catalytic three‐component Ugi reaction (see example). Different α‐amino amides are formed in good yields from aldehydes, primary amines, and isocyanides in the presence of phenyl phosphinic acid as the catalyst. The products will be useful for the synthesis of α‐amino acid derivatives and in diversity‐oriented

Three-Component Reaction of 3-Arylidene-3H-Indolium Salts, Isocyanides, and Alcohols [PDF]
A novel isocyanide-based multicomponent synthesis of alkyl aryl(indol-3-yl)acetimidates has been established. Starting from aryl(indol-3-yl)methylium tetrafluoroborates, aromatic isocyanides and alcohols, the imidates were obtained in moderate to very ...

Fast reaction limit of a three-component reaction–diffusion system [PDF]
The authors consider a three-component reaction-diffusion system with a reaction rate parameter, and investigate its singular limit as the reaction rate tends to infinity. The limit problem is given by a free boundary problem, which possesses three regions separated by the free boundaries.

Butterfly Catastrophe for Fronts in a Three-Component Reaction–Diffusion System [PDF]
The subject of the paper is the analysis of bifurcations of solutions for propagating fronts in a three-component one-dimensional reaction-diffusion model of the FitzHugh-Nagumo type, where single- and multiple-front patterns are basic dynamical states. The application of a combination of various analytical methods, such as singular perturbation theory,

A General Three-Component Alkyl Petasis Boron-Mannich Reaction [PDF]
Aryl amines are one of the most common moieties in biologically active molecules, and approximately 37% of drug candidates contain aromatic amines. Recent advancements in medicinal chemistry, coined as “escaping from flatland”, have led to a greater focus on accessing highly functionalized C(sp3)-rich amines to improve the physiochemical and ...
