Diastereoselective Synthesis of Fulleropyrrolidines from Suitably Functionalized Chiral Cyclobutanes

, 2016
The first diastereoselective synthesis of fulleropyrrolidines endowed with diastereomerically pure functionalized cyclobutanes is reported. The new C60-based cyclobutane derivatives 7a,b and 9 are suitably functionalized for further incorporation into ...

C(sp2)−H Cyclobutylation of hydroxyarenes enabled by silver-π-acid catalysis: diastereocontrolled synthesis of 1,3-difunctionalized cyclobutanes [PDF]

, 2023
Ring-opening of bicyclo[1.1.0]butanes (BCBs) is emerging as a powerful strategy for 1,3-difunctionalized cyclobutanes synthesis. However, the reported radical strain-release reactions are typically plagued with diastereoselectivity issues.

Stereochemical Control in the Matteson Reaction

Chemistry – A European Journal, EarlyView.
The Matteson homologation is a highly versatile method for the stereoselective insertion of carbenoids into boronic esters. Through iterative application of the process, complex chiral molecules can be synthesized. The stereoselectivity of the reaction is determined by a chiral diol incorporated in the boronic ester.

Cyclopropylamine‐Derived Distonic Iminium Radicals: Photoinduced Strategies in Chemo‐ and Stereo‐Selective Synthesis

Chemistry – A European Journal, EarlyView.
Cyclopropylamines have emerged as powerful photocatalytic building blocks. Upon light‐induced single‐electron oxidation, they undergo strain‐release ring opening to generate distonic iminium radicals that enable diverse transformations, including ring‐opening functionalization, formal [3 + 2] cycloadditions, radical cascades, and asymmetric bond ...

Reduction Process of Pt(IV) Complexes With Axial Acetato Ligands by Ascorbic Acid; Comparison of Experimental and Computational Tools

Chemistry – A European Journal, EarlyView.
Comparison of experimental and calculated rate constants for reduction of selected Pt(IV) complexes by ascorbic acid (AA) in water solution at pH = 7. ABSTRACT In the present work, the reduction mechanism of several Pt(IV) complexes bearing two axial acetato ligands by ascorbic acid (AA) was investigated.
