A 1,3,2-Diazaphospholene-Catalyzed Reductive Claisen Rearrangement

Nicolai Cramer, Pavel Alexandrovich Donets, John Henry Reed, Solène Florie Miaskiewicz

1,3,2-Diazaphospholenes (DAPs) are an emerging class of organic hydrides. In this work, we exploited them as efficient catalysts for very mild reductive Claisen rearrangements. The method is tolerant towards a wide variety of functional groups and operates ...

Enantioselective palladium(0)-catalyzed intramolecular cyclopropane functionalization: access to dihydroquinolones, dihydroisoquinolones and the BMS-791325 ring system

Nicolai Cramer, Tanguy Jean Daniel Saget, Pavel Alexandrovich Donets, Julia Pedroni

Taddol-based phosphoramidite ligands enable enantioselective palladium(0)-catalyzed C-H arylation of cyclopropanes. The cyclized products are obtained in high yields and enantioselectivities. The reported method provides efficient access to a broad range o ...

Ligand-Controlled Regiodivergent Nickel-Catalyzed Annulation of Pyridones

Nicolai Cramer, Pavel Alexandrovich Donets

The 1,6-annulated 2-pyridone motif is found in many biologically active compounds and its close relation to the indolizidine and quinolizidine alkaloid core makes it an attractive building block. A nickel-catalyzed CH functionalization of 2-pyridones and s ...

Nickel(0)-Catalyzed Enantioselective Annulations of Alkynes and Arylenoates Enabled by a Chiral NHC Ligand: Efficient Access to Cyclopentenones

Nicolai Cramer, Pavel Alexandrovich Donets, Joachim Sven Ernst Ahlin

Cyclopentenones are versatile structural motifs of natural products as well as reactive synthetic intermediates. The nickel-catalyzed reductive [3+2] cycloaddition of alpha,beta-unsaturated aromatic esters and alkynes constitutes an efficient method for th ...

Chiral Cp-Rhodium(III)-Catalyzed Asymmetric Hydroarylations of 1,1-Disubstituted Alkenes

Nicolai Cramer, Baihua Ye, Pavel Alexandrovich Donets

Metal-catalyzed functionalizations at the ortho position of a directing group have become an efficient bond-forming strategy. A wide range of transformations that employ Cp*Rh-III catalysts have been described, but despite their synthetic potential, enanti ...

Diaminophosphine Oxide Ligand Enabled Asymmetric Nickel-Catalyzed Hydrocarbamoylations of Alkenes

Nicolai Cramer, Pavel Alexandrovich Donets

Chiral trivalent phosphorus species are the dominant class of ligands and the key controlling element in asymmetric homogeneous transition-metal catalysis. Here, novel chiral diaminophosphine oxide ligands are described. The arising catalyst system with ni ...

Chiral Monodentate Trialkylphosphines Based on the Phospholane Architecture

Nicolai Cramer, Tanguy Jean Daniel Saget, Pavel Alexandrovich Donets

The development of efficient chiral monodentate phosphine ligands lags behind that of the bidentate congeners. This holds especially true for highly electron rich chiral phosphine analogues able to replace the ubiquitous tricyclohexylphosphine and tri-tert ...
