Synthesis of dienes from pyrrolidines using skeletal modification
Nature Communications, 2023 Saturated N-heterocyclic pyrrolidines are common in natural products, medicinal compounds and agrochemicals. However, reconstruction of their skeletal structures creating new chemical space is a challenging task, and limited methods exist for this ...

Asymmetric Synthesis of Polyfunctionalized Pyrrolidines from Sulfinimine-Derived Pyrrolidine 2-Phosphonates. Synthesis of Pyrrolidine 225C [PDF]
Organic Letters, 2006 [reaction: see text] The Horner-Wadsworth-Emmons reaction of aldehydes with sulfinimine-derived 3-oxo pyrrolidine phosphonates represents a new method for the asymmetric synthesis of ring-functionalized cis-2,5-disubstituted 3-oxo pyrrolidines.

Synchronized Imaging of Hydrogen Peroxide and Hydroxyl Radical in Pyroptosis and Epilepsy
Advanced Science, EarlyView.A dual‐responsive fluorescent probe, HH, enables synchronized visualization of H2O2 and •OH through spectrally resolved green and red channels. By tracking redox dynamics in pyroptosis and epilepsy models, HH reveals ROS elevation during seizure‐like pathology and supports evaluation of antioxidant and antiepileptic therapeutic interventions.

Angewandte Chemie, EarlyView.Highly electrophilic N‐radical cations enable efficient and selective H‐atom transfer (HAT) of unprotected amines. In this exceedingly practical strategy, simple CuCl catalyzes an interrupted Hofmann–Löffler–Freytag (HLF) reaction to afford δ desaturated amines, aza‐heterocycles, and C─H aminated alkanes without protecting groups.

Transient and intermediate carbocations in ruthenium tetroxide oxidation of saturated rings
Beilstein Journal of Organic Chemistry, 2019 The ruthenium tetroxide-mediated oxidation of cyclopentane, tetrahydrofuran, tetrahydrothiophene and N-substituted pyrrolidines has been studied computationally by DFT and topological (analysis of the electron localization function, ELF) methods.
