A genetic optimization strategy with generality in asymmetric organocatalysis as a primary target

Rubén Laplaza Solanas, Anne-Clémence Corminboeuf, Puck Elisabeth van Gerwen, Simone Gallarati

A catalyst possessing a broad substrate scope, in terms of both turnover and enantioselectivity, is sometimes called "general". Despite their great utility in asymmetric synthesis, truly general catalysts are difficult or expensive to discover via traditio ...

From Organic Fragments to Photoswitchable Catalysts: The OFF-ON Structural Repository for Transferable Kernel-Based Potentials

Matthew Wodrich, Anne-Clémence Corminboeuf, Frédéric Célerse, Simone Gallarati, Raimon Fabregat I De Aguilar-Amat, Veronika Juraskova

Structurally and conformationally diverse databases are needed to train accurate neural networks or kernel-based potentials capable of exploring the complex free energy landscape of flexible functional organic molecules. Curating such databases for species ...

Genetic Algorithms for the Discovery of Homogeneous Catalysts

Rubén Laplaza Solanas, Anne-Clémence Corminboeuf, Puck Elisabeth van Gerwen, Alexandre Alain Schöpfer, Simone Gallarati

In this account, we discuss the use of genetic algorithms in the inverse design process of homogeneous catalysts for chemical transformations. We describe the main components of evolutionary experiments, specifically the nature of the fitness function to o ...

Enriching the Computational Toolbox for Organocatalysis

Simone Gallarati

Organocatalysis has evolved significantly over the last decades, becoming a pillar of synthetic chemistry, but traditional theoretical approaches based on quantum mechanical computations to investigate reaction mechanisms and provide rationalizations of ca ...

OSCAR: an extensive repository of chemically and functionally diverse organocatalysts

Rubén Laplaza Solanas, Anne-Clémence Corminboeuf, Puck Elisabeth van Gerwen, Alberto Fabrizio, Sergio Vela Llausi, Simone Gallarati

The automated construction of datasets has become increasingly relevant in computational chemistry. While transition-metal catalysis has greatly benefitted from bottom-up or top-down strategies for the curation of organometallic complexes libraries, the fi ...

Harvesting the fragment-based nature of bifunctional organocatalysts to enhance their activity

Rubén Laplaza Solanas, Anne-Clémence Corminboeuf, Simone Gallarati

Bifunctional hydrogen-bond donors/amines are commonly encountered organocatalysts in asymmetric synthesis. Existing computational tools do not take full advantage of their modularity to suggest tailored designs because they generally rely on evaluating the ...

Mapping Catalyst‐Solvent Interplay in Competing Carboamination/Cyclopropanation Reactions

Nicolai Cramer, Matthew Wodrich, Anne-Clémence Corminboeuf, Miyeon Chang, Simone Gallarati

Group 9 metals, in particular Rh III complexes with cyclopentadienyl ligands, are competent C–H activation catalysts. Recently, a Cp*Rh III catalyzed reaction of alkenes with N -enoxyphthalimides showed divergent outcome based on the solvent, with carboami ...

Migrative Carbofluorination of Saturated Amides Enabled by Pd-Based Dyotropic Rearrangement

Qian Wang, Jieping Zhu, Anne-Clémence Corminboeuf, Hua Wu, Simone Gallarati, Guoqiang Yang

Directly editing an all-carbon quaternary carbon itself of nonstrained acyclic molecules remains underexploited despite the recent advances in the fields of both C–H and C–C bond activation. Herein, we report a palladium-catalyzed migrative carbofluorinati ...

Modular Synthesis of Benzocyclobutenes via Pd(II)-Catalyzed Oxidative [2+2] Annulation of Arylboronic Acids with Alkenes

Qian Wang, Jieping Zhu, Anne-Clémence Corminboeuf, Takuji Fujii, Simone Gallarati

Benzocyclobutenes (BCBs) are highly valuable compounds in organic synthesis, medicinal chemistry, and materials science. However, catalytic modular synthesis of functionalized BCBs from easily accessible starting materials remains limited. We report herein ...
