Structural effects in solvolytic reactions. VI. Rates and products in the acetolysis of substituted trans-2-phenylcyclopentyl tosylates and optically active derivatives. Nature of the aryl-assisted and the aryl-unassisted reaction pathways
Dual Activation of Unsaturated Amides with Schwartz's Reagent: A Diastereoselective Access to Cyclopentanols and N,O‐Dimethylcyclopentylhydroxylamines.
The concomitant generation of a nucleophilic and an electrophilic site from unsaturated Weinreb amide by using Cp2Zr(H)Cl) as the unique reagent was developed to promote a cyclisation reaction. The access to trans-2-substituted cyclopentanols or cyclopentylhydroxylamines can be selectively driven by a judicious choice of the cyclisationpromotor. An access to cis-3-substituted is also described.
sustainable electrochemical method for the synthesis of cyclic ethers and acyclic aldehydes from alkanols has been reported. This strategy has been successfully applied to cycloalkanols bearing different ring sizes and different types of nucleophiles. In addition, mechanistic investigations show that the reactions undergo sequential processes, including anodicoxidation, β-scission, and nucleophilic addition
