While Amazonian forests are extraordinarily diverse, the abundance of trees is skewed strongly towards relatively few 'hyperdominant' species. In addition to their diversity, Amazonian trees are a key component of the global carbon cycle, assimilating and storing more carbon...

Asymmetric Synthesis of Fluorinated Isoindolinones through Palladium-Catalyzed Carbonylative Amination of Enantioenriched Benzylic Carbamates.

Chemistry (Weinheim an der Bergstrasse, Germany)

Barrio P, Ibáñez I, Herrera L, Román R, Catalán S, Fustero S.
PMID: 26121312
Chemistry. 2015 Aug 03;21(32):11579-84. doi: 10.1002/chem.201500773. Epub 2015 Jun 29.

The asymmetric synthesis of fluorinated isoindolinones has been achieved by a palladium-catalyzed aminocarbonylation reaction of the corresponding α-fluoroalkyl o-iodobenzylamines. A base-mediated anti β-hydride elimination process was suggested to explain the partial erosion of the optical purity observed in some...

Depending on the pathological findings, up to 60% of prostate cancer patients who undergo radical prostatectomy (RP) will develop biochemical relapse and require further local treatment. Radiotherapy (RT) immediately after RP may potentially eradicate any residual localized microscopic disease...

Cell growth in a pinned soap froth.

Physical review. E, Statistical, nonlinear, and soft matter physics
