Uncovering the Mechanism of Azepino‐Indole Skeleton Formation via Pictet–Spengler Reaction by Strictosidine Synthase: A Quantum Chemical Investigation

ChemistryOpen, 2023
Strictosidine synthase (STR) catalyzes the Pictet–Spengler (PS) reaction of tryptamine and secologanin to produce strictosidine. Recent studies demonstrated that the enzyme can also catalyze the reaction of non‐natural substrates to form new alkaloid ...

Reaction mechanisms of alkali-activated materials

, 2021
: The Alkali-Activated Materials (AAM) are defined as materials obtained through the reaction between precursors and activators, and are separated into two classes depending on the products formed in the reaction, those rich in calcium, as the blast ...

Hydrogenation of CO₂ Promoted by Silicon-Activated H₂S: Origin and Implications

Molecules, 2020
Unlike the usual method of COx (x = 1, 2) hydrogenation using H2 directly, H2S and HSiSH (silicon-activated H2S) were selected as alternative hydrogen sources in this study for the COx hydrogenation reactions.

Reaction mechanisms in the 6Li+59Co system [PDF]

, 2009
The reactions induced by the weakly bound 6Li projectile interacting with the intermediate mass target 59Co were investigated. Light charged particles singles and $\alpha$-$d$ coincidence measurements were performed at the near barrier energies E_lab ...

Using Stop Motion Animations to Activate and Analyze High School Students’ Intuitive Resources about Reaction Mechanisms

Education Sciences, 2023
Mechanisms are part of the high school curriculum in many countries. Although research shows that university students struggle with mechanistic reasoning, very little is known about learning mechanisms in high school.
