ORGANIC CHEMISTRY. Catalytic asymmetric hydroamination of unactivated internal olefins to aliphatic amines.
Catalytic assembly of enantiopure aliphatic amines from abundant and readily available precursors has long been recognized as a paramount challenge in synthetic chemistry. Here, we describe a mild and general copper-catalyzed hydroamination that effectively converts unactivated internal olefins—an important yet unexploited class of abundant feedstock chemicals—into highly enantioenriched α-bran...

متن کاملAliphatic amines in Chesapeake Bay sediments
Aliphatic amines were determined in sediments and sediment pore waters from several contrasting sites in Chesapeake Bay. The aliphatic amines diethylamine, set-butylamine, n-propylamine, and i-propylamine were detected in a limited number of pore-water samples at concentrations generally less than 0.6 /IM. The occurrence of these amines showed no obvious correlation to other sediment geochemica...
متن کاملA Breakthrough in Monocot Transformation Methods.
The ability to generate transgenic plants without regard to cultivar or genotype can be considered a holy grail of cereal crop transformation. Despite years of effort, it has been remarkably difficult to develop efficient methods for transformation of cereals. The preferredmethodsgenerally involveAgrobacterium tumefaciens-mediated transformation of cultured tissue or immature embryos, followed ...
متن کاملApplication of Polypyrrole Coated Stainless-Steel Wire to the Headspace Solid-Phase Microextraction of Aliphatic Amines
The electrochemical coating technique was used for the preparation of a polypyrrole coating on a stainless-steel wire, and applied as a fibre for solid phase microextraction (SPME). The polypyrrole fibre was employed for analyzing four volatile aliphatic amines (ethylamine, propylamine, butylamine and pentylamine) in water by headspace SPME using gas chromatography-flame ionization detection (G...
