Synthesis of Pentacycloundecane (PCUD) Based Spiro-Pyrano-Cage Framework via Ring-Closing Metathesis
Publikováno v:
Molbank, Vol 2023, Iss 1, p M1567 (2023)
Here, we demonstrate a short synthetic route to pyrano cage systems containing pentacycloundecane units by employing ring-closing metathesis (RCM) as a key step. These cage systems were constructed starting with readily available starting materials b

Herein, we report a bisoxazole derivative as well as a bromo-substituted oxazole derivatives via a simple approach. The synthesis begins with an inexpensive and readily available starting material, such as 2,5-dimethoxybenzaldehyde, hydroquinone, and

We report a new synthetic approach to assemble spirothiazolidinediones via a [2 + 2 + 2] cyclotrimerization reaction and the derivatives were further functionalized through DA chemistry and click reaction. Using flow cytometry, it was shown for the f

The title racemic triquinane, C14H14Cl2O2, is composed of four five-membered rings, one of which is a tetrahydrofuran ring to which an allyl group on one side and a hydroxyl group on the other side are attached. The core of the triquinane unit has a

We demonstrate a new synthetic strategy toward star-shaped C3-symmetric molecules containing α-amino acid (AAA) derivatives and dipeptides. In this regard, trimerization and Negishi cross-coupling reactions are used as the key steps starting from re

The title N,N-dimethylthiohydantoin containing an N-methylated pthalimide group, C14H12N4O3S, arose from an unexpected reaction in a deep eutectic dimethylthiourea–tartaric acid solvent system. The mean planes of the ring systems are twisted at an
