Preparation of tertiary amines by the reaction of iminium ions derived from unsymmetrical aminals with zinc and magnesium organometallics.

Organic letters

Werner V, Ellwart M, Wagner AJ, Knochel P.
PMID: 25849577
Org Lett. 2015 Apr 17;17(8):2026-9. doi: 10.1021/acs.orglett.5b00801. Epub 2015 Apr 07.

We report a convenient one-pot preparation of polyfunctional tertiary amines, including various biorelevant phenethylamines or ephedrine derivatives, via the reaction of new functionalized iminium ions with a variety of zinc and magnesium organometallic reagents. These iminium ions were generated...

Fluorescence-detected circular dichroism spectroscopy of jet-cooled ephedrine.

Physical chemistry chemical physics : PCCP

Hong A, Jeong C, Jang H, Choi MC, Heo J, Kim NJ.
PMID: 26910410
Phys Chem Chem Phys. 2016 Mar 21;18(11):7762-7. doi: 10.1039/c5cp07438j.

The resonant two-photon ionization circular dichroism (R2PICD) spectrum represents the cumulative circular dichroism (CD) of one-photon excitation and the subsequent one-photon ionization, whereas the fluorescence-detected circular dichroism (FDCD) spectra exhibit only the CD of one-photon excitation, similar to conventional...

Effect of interscalene brachial plexus block on heart rate variability.

Korean journal of anesthesiology
