Dianionic Phase-Transfer Catalyst for Asymmetric Fluoro-cyclization [PDF]
, 2018 Inspired by the dicationic nature of the electrophilic fluorinating reagent, Selectfluor (1), we rationally designed a series of dicarboxylic acid precatalysts (2), which, when deprotonated, act as anionic phase-transfer catalysts for asymmetric ...

Non-native Radical Cyclization Catalyzed by a B12-Dependent Enzyme [PDF]
, 2023 Despite the unique reactivity of vitamin B12 and its derivatives, B12-dependent enzymes remain underutilized in biocatalysis. In this study, we repurpose the B12-dependent transcription factor CarH to enable non-native radical cyclization reactions.

Asymmetric Nazarov cyclizations [PDF]
Tetrahedron, 2011 The Nazarov cyclization1 is described as the 4 π electron conrotatory cyclization of a pentadienyl cation. The past 20 years have brought resurgent interest in this reaction most likely due to the realization that it can provide rapid and efficient access to multisubstituted cyclopentenones with excellent stereochemical control at two (or even three ...
