Org Lett. 2013 Dec 06;15(23):5940-3. doi: 10.1021/ol4027683. Epub 2013 Nov 15.

A simple and efficient palladium-catalyzed oxidative coupling between 2-alkynyl anilines and allylic alcohols is described by using cheap and green dioxygen as the oxidant. These cross-couplings have a large functional group tolerance and are of higher reactivity toward electron...

Metal-free nitroxyl radical-mediated β-C(sp.

Chemical communications (Cambridge, England)

Qian P, Deng Y, Mei H, Han J, Pan Y.
PMID: 28229143
Chem Commun (Camb). 2017 Mar 07;53(20):2958-2961. doi: 10.1039/c7cc00145b.

The first metal-free nitroxyl-radical-mediated β-amination of saturated ketones by using heteroaryl halides as amide precursors has been developed. This reaction proceeds through a cascade α-aminoxylation/Cope-like elimination/aza-Michael addition sequence to afford β-amino ketone derivatives with excellent yields. TEMPO plays multiple...

Efficient hydroxymethylation reactions of iodoarenes using CO and 1,3-dimethylimidazol-2-ylidene borane.

Organic letters

PMID: 28911380
J Food Drug Anal. 2015 Jun;23(2):253-259. doi: 10.1016/j.jfda.2014.10.006. Epub 2014 Dec 03.

Volatile extracts from the seeds of Dendranthema nankingense Hand.-Mazz. and Borago officinalis L. were prepared using simultaneous distillation and extraction, and analyzed with gas chromatography-mass spectrometry on two capillary gas chromatography columns of different polarity. Ninety-five volatile compounds were...

Highly Enantioselective Construction of Fluoroalkylated Quaternary Stereocenters via Organocatalytic Dehydrated Mannich Reaction of Unprotected Hemiaminals with Ketones.

Organic letters
