The polyphenolic and hydroxycinnamate contents of whole coffee fruits from China, India and Mexico [PDF]

, 2013
Air dried whole coffee fruits, beans and husks from China, India and Mexico were analysed for their chlorogenic acids (CGA), caffeine, and polyphenolic content. Analysis was by HPLC and Orbitrap exact mass spectrometry.

Attractive aerobic access to the α,β-unsaturated acyl azolium intermediate: oxidative NHC catalysis via multistep electron transfer [PDF]

, 2016
To replace high molecular weight oxidants with air (O2) we introduce multistep electron transfer NHC catalysis. The method provides a general and selective oxidation of the α,β-unsaturated aldehyde derived homoenolate to the synthetically useful α,β ...
