A study towards the synthesis of (-)-atrop-abyssomicin C core [PDF]

open access: yesJournal of the Serbian Chemical Society, 2021
An attempt to synthesize the cyclohexane core of antibiotic abyssomicin C is described. The initial, protecting group-free approach (relying on internal protection) failed and had to be modified, in order to allow for efficient deprotection of the acid ...

Efficient Synthesis of Isoquinoline Derivatives through Sequential Cyclization–Deoxygenation Reaction of 2-Alkynylbenzaldoximes

open access: yesSynOpen, 2022
We describe a novel, simple, robust, and efficient cyclization/deoxygenation approach for the synthesis of functionalized isoquinoline derivatives. Over the course of continued studies on o-alkynylbenzaldoxime cyclization reactions, the formation of ...

Study on by-products synthesis of powder coating polyester resin catalyzed by organotin

open access: yese-Polymers, 2023
In the production of powder-coating polyester, a strong odor emanates from the water, prompting us to investigate its composition and origin. We studied the process of powder coating epoxy/polyester 50/50, which employs butyl tin tris (2-ethyl hexanoate)
