Cycloaddition reactions of nitrosoalkenes, azoalkenes and nitrile oxides mediated by hydrotalcite [PDF]

open access: yes, 2012
Mg:Al 3:1 hydrotalcite (Ht), used in catalytic quantities, promotes the generation of nitrosoalkenes, azoalkenes and nitrile oxides. These can be intercepted in situ by heterocycles and olefins in [4+2] and [3+2] cycloaddition reactions, producing ...

Synthesis, Conformation and Antiproliferative Activity of Isothiazoloisoxazole 1,1-dioxides [PDF]

open access: yes, 2016
Sixteen new isothiazoloisoxazole 1,1-dioxides, one new isothiazolotriazole and one new isothiazolopyrazole have been synthesised by using 1,3-dipolar cycloadditions to isothiazole 1,1-dioxides.

Photoactivated Proximity Protein Labeling Reveals Enhanced Tumor Retention of a D‐Peptide‐Ruthenium Prodrug Conjugate

open access: yesAdvanced Healthcare Materials, EarlyView.
Six stereoisomeric ruthenium‐peptide conjugates were synthesized and characterized, which showed high potential in photoactivated chemotherapy (PACT) and proximity protein labeling. Abstract Amino acid chirality is known to influence the biological properties of peptide‐containing prodrugs.

NMR studies on 1,3-dipolar cycloaddition of nitrile oxides to norbornenes

open access: yes, 2013
The 1,3-dipolar cycloaddition reaction of nitrile oxides to norbornenes substituted with an acrylate-derived moiety was examined. Only adducts to norbornene system were formed with a good exo selectivity and complete site-selectivity.

A competition between N---O and C---O through space interactions in the crystal structures of 3,3'-dinitro-2,2'-bipyridine N-oxides and N,N'-dioxides [PDF]

open access: yes, 2007
The crystal structures of a series of 3,3’-dinitro-2,2’-bipyridine N-oxides and N,N’-dioxides consistently show 1,5 interactions between nitro oxygen atoms and aromatic carbon atoms ((ON)O---C: 2.623(2)-2.839(2) Å) while there are also 1,6 interactions ...
