ABSTRACT
N-Methyl-3-phenyl-norbornan-2-amine (N-methyl-3-phenylbicyclo[2.2.1]heptan-2-amine, Camfetamine(™) ) is available from a number of online legal highs/research chemicals' vendors. Although it was developed as an analeptic by Merck in the early 1960s, it was never commercialized. However, the Association of Independent Research Chemical Retailers (AIRCR), an umbrella organization for a number of online vendors, has redeveloped it for use as a recreational drug. N-Methyl-3-phenyl-norbornan-2-amine is closely related to fencamfamine which has been widely used as a central nervous system (CNS) stimulant and appetite suppressant. In this paper we describe the synthesis of N-methyl-3-phenyl-norbornan-2-amine, its characterization and interpretations of its electron impact, and electrospray ionization mass spectra.

The first synthesis of the 2,3-isomers of MDPV, butylone and methylone is reported. The isomers were characterised by (1)H and (13)C NMR spectroscopy and compared to the corresponding 3,4-isomers. A GC method is described which separates the 3,4- and the 2,3-isomers from each other. IR spectra of the 2,3-isomers are also compared with the corresponding 3,4-isomers. Two seized drug samples were analysed by GCMS and the samples were found to contain the 3,4-isomers.
ABSTRACT
3ß-(4-Fluorobenzoyloxy)tropane (3ß-FBT, fluorotropacocaine) was first reported by Finnish authorities to the European Monitoring Centre for Drugs and Drug Addiction (EMCDDA) via the Early Warning System (EWS) in 2008 and our own laboratory tentatively identified it in 2010 in several products purchased from head shops. Very little is known about this cocaine-like drug and, as no reference standards were available, we have synthesized and characterized both 3ß-FBT and its 3α isomer for use as reference standards. The two compounds are separable by gas chromatography (GC) but their electron-impact (EI) mass spectra were found to be almost identical. ¹9F NMR spectroscopy was also found to be a useful technique for distinguishing the two isomers.
