Four isomeric dialdehydes 4, readily available from cycloaddition of propiolic aldehyde (2) to 1,2,4,5-hexatetraene (1), were separated by chromatography and recrystallization, and were characterized by their spectroscopic data. The individual isomer

In our effort to prepare [m.n]cyclophanes carrying functional groups in their molecular bridges, the thiacyclophanes 14, 19, 20, and 21 have been prepared by simple routes from the pseudo-gem dibromide 10a and the corresponding bis-thiol 10b. The tri
In June 2018, 15 'Spice-like' herbal products from German language internet shops were analyzed. In total, three different synthetic cannabinoids (SCs) were identified by gas chromatography-mass spectrometry (GC-MS). Two of the active ingredients wer

Starting with the parent compound [2.2.2]paracyclophane several routes were developed to synthesize its 4-vinyl derivative. From the 4-aldehyde and the bromomethyl derivative the stilbenophanes were prepared which photocyclize to the phenanthrenophan

In February 2015, 13 “spice-like” products, available on the German market, were analyzed. In total, eight different synthetic cannabinoids were identified by gas chromatography–mass spectrometry (GC–MS), namely 5-fluoro-AB-PINACA, AB-CHMINAC

One of the main reasons for the rise in popularity of synthetic cannabinoids (SCs) is their ability to remain unrecognized in conventional drug screenings. Due to their structural diversity, caused by the constant introduction of new substances to ci

The [2.2]paracyclophane moiety is used as a spacer to connect the ends of a hex-3-ene-1,5-diyne unit, a p-system that on thermolysis usually cycloaromatizes to a benzene ring (Bergman cyclization). For the preparation of the pseudo-geminally-bridged
