Abstract:
Substituted 1H-pyrazolo[3,4-b]pyridine-4- and 1H-pyrazolo[3,4-b]pyridine-6-carboxamides have been synthetized through a Doebner–Ugi multicomponent reaction sequence in a convergent and versatile manner using diversity generation strategies: combination of two multicomponent reactions and conditions-based divergence strategy. The target products contain as pharmacophores pyrazolopyridine and peptidomimetic moieties with four points of diversity introduced from readily available starting materials including scaffold diversity. A small focused compound library of 23 Ugi products was created and s

Abstract:
In continuation of our recent research on the development of novel multicomponent reactions with isocyanides, we have used, for the first time, enols as the acid components in Ugi- and Passerini-type reactions. Thus, electron-poor pyrrolidinodiones react with aldehydes, amines, and isocyanides to give the enaminic four-component adducts. Conversely, in the absence of the amine component, careful control of the reaction conditions allows the involvement of one or two molecules of isocyanide to afford, selectively, either Passerini-type or pseudo-enol-Ugi-type products. These unprecedented conde

Abstract:
Les réactions de type Ugi sont connues depuis une cinquantaine d'années. Ces réactions multicomposants mettent en jeu un aldéhyde, une amine, un isonitrile ainsi qu'un dérivé acide (acide carboxylique ou phénol activé). Dans ces travaux, la structure électronique des isonitriles, composé au coeur de ces réactions a été étudiée. La forme carbénique RN=C s'est révélée majoritaire contrairement à toute attente. La linéarité de la molécule a pu être interprétée grâce aux contributions des formes minoritaires. La seconde partie s'est focalisée sur l'étude théorique et expérimentale des couplages de

La réaction de macrocyclisation est une transformation fondamentale en chimie organique de synthèse. Le principal défi associcé à la formation de macrocycles est la compétition inhérente avec la réaction d’oligomérisation qui mène à la formation de sousproduits indésirables. De plus, l’utilisation de conditions de dilutions élevées qui sont nécessaires afin d’obtenir une cyclisation “sélective”, sont souvent décourageantes pour les applications à l’échelle industrielle.

Abstract:
Technology for large scale catalytic hydrogen generation from hydrocarbons is quite mature and most reactors are of the fixed catalyst bed-type operated in a steady-state, continuous-flow (CF) regime. However, simple miniaturization of these reactors for portable and distributed applications has proven difficult because of 1) the poor process scale-down, 2) sequential uni-functional design not suitable for miniaturization and system integration, and 3) poor reaction yields due to fundamental mismatch between the time scales of the catalytic chemistry and the transport processes.
