Direct, catalytic, and regioselective synthesis of 2-alkyl-, aryl-, and alkenyl-substituted N-heterocycles from N-oxides.

Oleg V Larionov et al.

Organic letters, 16(3), 864-867 (2014-01-15)

A one-step transformation of heterocyclic N-oxides to 2-alkyl-, aryl-, and alkenyl-substituted N-heterocycles is described. The success of this broad-scope methodology hinges on the combination of copper catalysis and activation by lithium fluoride or magnesium chloride. The utility of this method

Time-of-flight accurate mass spectrometry identification of quinoline alkaloids in honey.

Tamara Rodríguez-Cabo et al.

Analytical and bioanalytical chemistry, 407(20), 6159-6170 (2015-06-05)

Time-of-flight accurate mass spectrometry (TOF-MS), following a previous chromatographic (gas or liquid chromatography) separation step, is applied to the identification and structural elucidation of quinoline-like alkaloids in honey. Both electron ionization (EI) MS and positive electrospray (ESI+) MS spectra afforded
