Presented live November 2, 2022
Step inside the Parasram Lab at New York University for a look at some of their latest research.
In this webinar, Professor Marvin Parasram will discuss data from his laboratory’s recent publication, “Anaerobic Heteroatom Transfer Reactions Using Photoexcited Nitroarenes.” The research features developments on the anaerobic cleavage of alkenes into carbonyl compounds using nitroarenes as oxygen transfer reagents under visible light. This approach is a safe and practical alternative to mainstream oxidative cleavage protocols, such as ozonolysis and the Lemieux–Johnson reaction.
As an attendee, you will learn more about:
How a wide range of alkenes possessing oxidatively sensitive functionalities underwent anaerobic cleavage to generate carbonyl derivatives with high efficiency and regioselectivity, using the Advion Interchim Scientific puriFlash® 5.250 Preparative HPLC system.
Mechanistic studies support that the transformation occurs via direct photoexcitation of the nitroarene followed by a nonstereospecific radical cycloaddition event with alkenes.
How this process leads to 1,3,2- and 1,4,2-dioxazolidine intermediates that fragment to give the carbonyl products, using the Advion Interchim Scientific expression Compact Mass Spectrometer.
How a combination of radical clock experiments and in situ photoNMR spectroscopy revealed the identities of the key radical species and the putative aryl dioxazolidine intermediates, respectively.Watched the video and ready to learn more?

Helium shortages are not new – annually, scientists see the cost of helium rise and fall like the stock market. Except this isn’t just a financial impact. Global helium shortages threaten to derail research and essential industry functions, taking down GC and high-field NMR instruments, bringing a once state-of-the-art lab down to a bare-bones facility.
This whitepaper explores the use of alternative reaction monitoring technology, including the expression® CMS (Compact Mass Spectrometer), Plate ExpressTM TLC Plate Reader, and ASAP® probe for liquid and solid samples – all helium-free alternatives for the chemistry laboratory.
Reaction Monitoring Capabilities at the Bench:
The expression® CMS offers an ideal reaction monitoring solution that will live on long beyond the helium shortage and become a centerpiece of the lab. The system offers a complete solution for:
Batch and flow chemistry
Fast compound identification and purity determination
…with little or no sample preparation required, and many novel sample introduction interfaces
This webinar features several useful tools to simplify or even eliminate the sample preparation involved prior to mass spectrometry. In this educational session you will learn about several prep-free mass spec techniques that are available, and how to select which method is best for your analysis. Advion will share their perspectives on some of the new tools and protocols to minimize and simplify sample preparation. You’ll learn how to reduce your time in the lab and see your mass spec results in as little as 30 seconds!
As an attendee, you will learn more about:
How to select the best tools for sample introduction based on your compound
How new tools can reduce or eliminate sample preparation for results in <30 seconds
New workflows to maximize your time in the lab by simplifying complex processes

Abstract
We developed a simple way to create 2D conductive nanostructures with dielectric cores and conductive surfaces based on polyethylene with in-chain thiophene groups. Generally, thiophene-based polymers show great conductive properties, but exhibit a poor processability. Here, we use the crystallization of a polyethylene chain with precisely distributed thiophene groups as the platform for a self-organization of a lamellar structure. During crystallization, thiophene groups are expelled to the crystal surface. Subsequent copolymerization with 3,4-ethylenedioxythiophene (EDOT) molecules finally yields 2D platelets with a conductive surface. The electric properties of the surface are demonstrated by conductivity measurements. Given the molecular structure of the polymer, it can be assumed that the conductive layer consists of only one monoatomic layer of polymerized thiophene. We thus show a new way to create an ultra-thin, conductive surface on a polymer surface in just a few steps. Hence, the method presented here opens up a wide range of possibilities to produce complex, nanoscale electronic structures for microelectronic applications.

Deuterium exchange has been demonstrated to provide additional information to accurate mass measurement and collision‐induced dissociation on unknown chemical structures. An enhanced method for rapid deuterium exchange could make this technique more routine for structural elucidation. Open port sampling interface mass spectrometry (OPSI‐MS) with an aprotic solvent offers a rapid method for performing deuterium incorporation.

Abstract
We previously identified and characterized an intramolecular trans-sialidase (IT-sialidase) in the gut symbiont Ruminococcus gnavus ATCC 29149, which is associated to the ability of the strain to grow on mucins. In this work we have obtained and analyzed the draft genome sequence of another R. gnavusmucin-degrader, ATCC 35913, isolated from a healthy individual. Transcriptomics analyses of both ATCC 29149 and ATCC 35913 strains confirmed that the strategy utilized by R. gnavus for mucin-degradation is focused on the utilization of terminal mucin glycans. R. gnavus ATCC 35913 also encodes a predicted IT-sialidase and harbors a Nan cluster dedicated to sialic acid utilization. We showed that the Nan cluster was upregulated when the strains were grown in presence of mucin. In addition we demonstrated that both R. gnavus strains were able to grow on 2,7-anyhydro-Neu5Ac, the IT-sialidase transglycosylation product, as a sole carbon source. Taken together these data further support the hypothesis that IT-sialidase expressing gut microbes, provide commensal bacteria such as R. gnavus with a nutritional competitive advantage, by accessing and transforming a source of nutrient to their own benefit.
Mass spectrometry analysis was performed on the Advion Interchim Scientific® expression® Compact Mass Spectrometer (CMS) and the data was evaluated using Advion Interchim Scientific® Data Express software.
