Enzymatic intermolecular Diels-Alder reactions in synthesis: From nature to design [PDF]

Tetrahedron Chem, 2022
The Diels-Alder (D-A) reaction is one of the most critical chemical transformations to construct C–C bonds with predictable regio- and stereo-selectivities. It has been widely used as a retrosynthetic disconnection in synthetic chemistry.

A Simple Entry to the 5,8-Disubstituted Indolizidine Skeleton via Hetero Diels-Alder Reaction [PDF]

Molecules, 2023
The 5,8-disubstituted indolizidines are the largest family of indolizidines isolated from the skin of amphibians. These compounds exhibit interesting biological activities such as noncompetitive blockers of nicotinic receptors.

Thermally Induced Intramolecular Diels–Alder Reaction of Furan-Tethered Methylenecyclopropanes [PDF]

Molecules
The substantial ring strain and activated double bonds render methylenecyclopropanes (MCPs) potential substrates for Diels–Alder (DA) reactions. In this work, we present a thermally induced intramolecular Diels–Alder (IMDA) reaction utilizing furan ...

Exploring the Limits of Reactivity of N-Methyl-1,2,4-triazoline-3,5-dione (MeTAD) with Disubstituted Bicycloalkadienes in the Homo-Diels–Alder Reaction

Organics, 2022
The [2+2+2] cycloaddition (homo-Diels–Alder reaction) of N-substituted 1,2,4-triazoline-3,5-diones (TADs) with bicycloalkadienes produces strained heterocyclic compounds.

Reversible Diels–Alder Reactions with a Fluorescent Dye on the Surface of Magnetite Nanoparticles

Molecules, 2021
Diels–Alder reactions on the surface of nanoparticles allow a thermoreversible functionalization of the nanosized building blocks. We report the synthesis of well-defined magnetite nanoparticles by thermal decomposition reaction and their ...
