Recent progress in the synthesis of six-membered aminocyclitols (2008-2017) [PDF]

, 2018
Aminocyclitols are of interest as glucosidase inhibitors, as probes for the study of pseudoglycosyltransferases, and as potential therapeutics for the treatment of Gaucher’s disease.

An optimised scalable synthesis of H2O@C60and a new synthesis of H2@C60

, 2014
New high-yielding synthetic routes to the small-molecule endofullerenes H2O@C60, D2O@C60 and H2@C60 are described. The use of high temperatures and pressures for the endohedral molecule incorporation are avoided.

Highly Regioselective 1,3-Dipolar Cycloaddition of Nitrilimines and Thioaurones Towards Spiro-2-Pyrazolines: Synthesis, Characterization, and Mechanistic Study

Reactions
In this paper, we report a highly regioselective 1,3-dipolar cycloaddition (1,3-DC) reaction of nitrilimines with thioaurone derivatives that afforded the hitherto unreported spiropyrazolines. Spectroscopic and spectrometric data were utilized to confirm

Synthesis of Novel Spiro-Isoxazolidine Derivatives of 9α-Hydroxyparthenolide

Molbank
The 1,3-dipolar cycloaddition reaction was applied to 9α-hydroxyparthenolide, an important sesquiterpene component of Anvillea radiata that was extracted directly from plant material collected in Morocco.

Dibenzazepine Bridged Network Polymeric Phthalocyanines as Degradable Heterogeneous Photocatalysts

Angewandte Chemie International Edition, EarlyView.
Dibenzazepine photodynamic bridge has been introduced to zinc and cobalt networks phthalocyanines (NP‐Pcs) to obtain degradable heterogeneous photocatalysts. For the first time, light irradiation plays a key role in “design, use and degradation” of NP‐Pcs.
