A Modular and Diastereoselective 5+1 Cyclization Approach to N-(Hetero)Aryl Piperidines.

open access: yesJournal of the American Chemical Society, 2019
A new general de novo synthesis of pharmaceutically important N-(hetero)aryl piperidines is reported. This protocol uses a robustly diastereoselective reductive amination/aza-Michael reaction se-quence to achieve rapid construction of complex ...

Pyrrolidines and Piperidines by Ligand‐Enabled Aza‐Heck Cyclizations and Cascades of N‐(Pentafluorobenzoyloxy)carbamates

open access: yesAngewandte Chemie, 2018
Ligand‐enabled aza‐Heck cyclizations and cascades of N‐(pentafluorobenzoyloxy)carbamates are described. These studies encompass the first examples of efficient non‐biased 6‐exo aza‐Heck cyclizations. The methodology provides direct and flexible access to

Regio- and Stereoselective Palladium-Catalyzed C(sp3)-H Arylation of Pyrrolidines and Piperidines with C(3) Directing Groups.

open access: yesOrganic Letters, 2018
The selective synthesis of cis-3,4-disubstituted pyrrolidines and piperidines is achieved by a Pd-catalyzed C-H arylation with excellent regio- and stereoselectivity using an aminoquinoline auxiliary at C(3). The arylation conditions are silver free, use

Alleviation of Aging‐Related Hallmarks in a Mouse Model of Progeria via a Nanoparticle‐Based Artificial Transcription Factor

open access: yesAdvanced Functional Materials, EarlyView.
Oct4‐nanoscript, a biomimetic nanoparticle‐based artificial transcription factor, precisely regulates cellular rejuvenation by activating Oct4 target genes, restoring epigenetic marks, and reducing DNA damage. In a progeria model, it effectively rescued aging‐associated pathologies and extended lifespan.
