Synthesis and Properties of Chelating N-Heterocyclic Carbene Rhodium(I) Complexes: Synthetic Experiments in Current Organometallic Chemistry.
(© 2011 The American Chemical Society and Division of Chemical Education, 2011-03)
The preparation and characterization of two air-stable Rh(I) complexes bearing a chelating N-heterocyclic carbene (NHC) ligand is described. The synthesis involves the preparation of a Ag(I)-NHC complex and its use as ...
Template Effects in SN2 Displacements for the Preparation of Pseudopeptidic Macrocycles
(Wiley, 2012-02)
Macrocyclisation reactions of C2-symmetric pseudopeptides containing central pyridine-derived spacers are affected by the presence of different anions. The selection of the proper anion gives excellent results for the ...
Rational Design of Simple Organocatalysts for the HSiCl3 Enantioselective Reduction of (E)-N-(1-Phenylethylidene)aniline
(MDPI, 2021-11-18)
Prolinamides are well-known organocatalysts for the HSiCl3 reduction of imines; however,
custom design of catalysts is based on trial-and-error experiments. In this work, we have used
a combination of computational ...
Iridium NHC based catalysts for transfer hydrogenation processes using glycerol as solvent and hydrogen donor
(American Chemical Society, 2011-10)
A series of iridium and ruthenium N-heterocyclic carbene based catalysts of general formula [IrI2(AcO)(bis-NHC)] or [Ru(η6-arene)(NHC)CO3] have been tested in the reduction of several organic carbonyl compounds using ...
A Y-Shaped tris-N-heterocyclic carbene for the synthesis of simultaneously chelate-monodentate dipalladium complexes
(American Chemical Society, 2011-11)
A Y-shaped tris-NHC ligand has been obtained and coordinated to palladium, affording metal complexes with novel topological properties. The tris-NHC ligand is capable of coordinating the two metals, affording two different ...
Stereoselective Synthesis of the Cytotoxic 14-Membered Macrolide Aspergillide A
(American Chemical Society, 2010)
A stereoselective synthesis of the cytotoxic 14-membered macrolide aspergillide A has been performed. The preparation of a cis-2,6-disubstituted tetrahydropyran ring via stereoselective reduction of an intermediate cyclic ...
Non-Polymeric Nanogels as Versatile Nanocarriers: Intracellular Transport of the Photosensitizers Rose Bengal and Hypericin for Photodynamic Therapy
(American Chemical Society, 2021-04-19)
The use of nanocarriers for intracellular transport of actives has been extensively studied in recent years and represents a central area of nanomedicine. The main novelty of this paper lies on the use of nanogels formed ...
Localized intracellular pH measurement using a ratiometric photoinduced electron-transfer-based nanosensor
(Wiley, 2012-09)
Intracellular analysis: Changes in the concentration of hydrogen ions can lead to cellular dysfunction. Thus, quantification of the intracellular pH in localized compartments (see A and B) is important. A pH nanosensor ...
Design and synthesis of pironetin analogues with simplified structure and study of their interactions with microtubules
(Elsevier, 2011-05)
The preparation of a series of pironetin analogues with simplified structure is described. Their cytotoxic activity and their interactions with tubulin have been investigated. It has been found that, while less active than ...
Lignoids Isolated from Nectandra turbacensis (Kunth) Nees (Lauraceae)
(Academy of Chemistry of Globe Publications, 2016)
A new 7,8-secolignan, as well as seven known compounds; were isolated from Nectandra turbacensis
(Kunth) Nees (Lauraceae) (leaves and root bark). These compounds were identified as, one secolignan, turbacenlignan A (1); ...
