N‐Containing Carbon Materials in Metal‐Free and Non‐Noble Metal Liquid Phase Heterogenous Catalysis
Advanced Synthesis &Catalysis, EarlyView.Over 100 examples of non‐noble metal supported on N‐containing and metal‐free N‐containing carbon catalysts are discussed. Particular emphasis is put on how different N‐functionalities influence catalyst performance and stability. Preparation procedures are also examined, with a strong focus on how the heat treatment temperature influences N ...

Angewandte Chemie, EarlyView.A dimethylsulfoniopropionate lyase (DddK) was identified as an efficient aza‐Michaelase for the addition of amines to acrylate. Screening 74 amines with wild‐type DddK and its W26G variant yielded N‐substituted and N,N‐disubstituted β‐amino acids in 30%–93% isolated yield.

Experimental study of local anesthetic and antiarrhythmic activities of fluorinated ethynylpiperidine derivatives [PDF]
Brazilian Journal of Medical and Biological ResearchThe chemical structure of piperidine has a unique ability to combine with other molecular fragments. This fact makes it possible to actively use it as an effective basis for the creation of new drug-like substances.
