Cannabis through the looking glass: chemo- and enantio-selective separation of phytocannabinoids by enantioselective ultra high performance supercritical fluid chromatography [PDF]

, 2017
By using the Inverted Chirality Columns Approach (ICCA) we have developed an enantioselective UHPSFC method to determine the enantiomeric excess (ee) of (-)-Δ(9)-THC in medicinal marijuana (Bedrocan®).

Bioinspired Synthesis of Twin abeo‐Steroids Bufogargarizins A and B via a Divergent Intramolecular Aldol Addition Reaction

Angewandte Chemie, EarlyView.
Twin natural products. This manuscript describes a concise biomimetic synthesis of twin abeo‐steroids bufogargarizins A and B with an unusual [7.5.6.5] and [5.7.6.5] skeletons in 19 steps (LLS). The described synthetic approach features the application of a bioinspired regiodivergent intramolecular aldol addition reaction and a selective singlet oxygen‐

The Puzzle of the New Type of Intermediate in the Course of [2 + 2] Cycloaddition with the Participation of Conjugated Nitroalkenes: MEDT Computational Study

Molecules
The phenomena of regio- and stereoselectivity and the molecular mechanism of the [2 + 2] cycloaddition reaction between (E)-2-arylnitroethenes and the ynamine molecular system were analyzed using wb97xd/6-311 + G(d) (PCM) quantumchemical calculations. It

Ceramide structural features required to stimulate ABCA1-mediated cholesterol efflux to apolipoprotein A-I

Journal of Lipid Research, 2006
Ceramide is a component of the sphingomyelin cycle and a well-established lipid signaling molecule. We recently reported that ceramide specifically increased ABCA1-mediated cholesterol efflux to apolipoprotein A-I (apoA-I), a critical process that leads ...

Synthesis of Enantiopure [3]Cyclorubicenes

Angewandte Chemie, EarlyView.
Herein, we present a high yielding synthesis of enantiopure [3]cyclorubicene, which is a potential precursor for a Haeckelite nanotube. This macrocycle was studied for its electronic and chiroptical properties and exhibits one of the highest dissymmetry values reported for a nanohoop.
