The Structural Determination, Total Synthesis and Endochronicity of Thiotimoline

The natural product thiotimoline was isolated from the bark of Rosaceae Karlsbadensis rufo and its structure was unambiguously determined by time-resolved X-ray crystallomancy and spectroscopy. A total synthesis of thiotimoline was conducted following a convergent strategy. The pivotal transformations in this synthesis were a tandem Suzuki-Miyaura/Schinkenfaust radical cross-spifflication, a Szymankowszczyzna allylic inquisition and a [3+2+3+2] Puccini-Gershwin echocyclisation in A♭ major. An unnatural isomer of thiotimoline was also synthesised, and a theory of kairality and chronomers is presented and discussed.

Synthesis and Characterization of a Novel Nitrotoluene Polymer: TNTP

The attractive physical properties and widespread availability of 2,4,6-trinitrotoluene (TNT) make it a popular commodity chemical. In accordance with the maxim that longer things are more appealing, it stands to reason that polymerising TNT should improve its utility. Herein, we report the first synthesis of poly(TNT), and an appraisal of its properties and commercial potential.

On the Bending of SPOONS

The following article constitutes a preliminary trial of a chemistry-specific artificial intelligence chatbot called “ChatCsp3”. This bot is being trained to take dense chemical jargon (left column) and make it accessible to the general public (right column).

The Total Synthesis of Monoalizeamine D

We report the first total synthesis of the supernatural product monoalizeamine D via a 14-step pathway. Our synthetic approach relies heavily on photocatalysis and radical intermediates. By preparing both E and Z isomers of this compound, we have conclusively resolved the ambiguity concerning the orientation of the C15–C16 olefin.

The Synthesis of Hexazine by use of Azide-Azide Click Chemistry with an Ammoniumide Catalyst

We report the first synthesis and comprehensive characterisation of hexazine, last in the series of 6-membered nitrogen heterocycles. A novel azide-azide click reaction was developed to facilitate this synthesis. Hexazine may serve as a non- carcinogenic alternative solvent to benzene, function as a mild amine-base, and even act as a weak nucleophile for further synthesis. The detailed exploration of such is left as an exercise for the reader.

Frank Furious and the Very Cross Coupling: A Pre-Emptive Eulogy

 It is with sadness, confusion, and relief that the chemistry community prepares to farewell one of its most colourful members. Frank Furious (1974–TBA) was, and technically still is, an Austrian American synthetic chemist, known for his work in palladium catalysis, and for dancing naked on the bar at an ACS annual meeting in 1998. He is currently in a coma at St Ethylbert’s Hospital in Luton, following a serious lab accident earlier this week.

Novel Treatment of Electrile Dysfunction and Rigor Moietis with Energy Transfer Catalysis

Did you know that one in ten molecules suffers from electrile dysfunction? Electrile dysfunction (ED) is a mechanistic condition in which the electron density within a molecule becomes constricted, preventing it from reaching a functional group. The result is a loss of steric rigidity which quite frequently causes impaired reactivity. Conversely, rigor moietis (RI) can occur as a result of orbital scrambling. This work describes a treatment for ED and RI using energy transfer catalysis..

All-Purpose Equipment for Chemical Synthesis

Are you tired of cleaning glassware? Are your fingers burning from all that acetone? Do you wish that your lab partner would just shut up and stop spilling your hard-earned product on the floor? Well, we can’t prevent the last one, but with some novel equipment designed in collaboration with top boron chemists, interior designers, and glass blowers, we have revolutionized laboratory glassware.
