Direct Catalytic Asymmetric Synthesis of Pyrazolidine Derivatives

The importance and increased demand of pharmaceutically active azaheterocycles has urged the development of inexpensive and environmentally benign catalytic asymmetric technologies. 2] In this context, the pyrazolidine and pyrazoline structural motif is present in several compounds with significant bioactivities, such as anti-inflammatory, antidepressant, anticancer, antibacterial and antiviral...

Synthesis and Characterization of Quinoidal Diketopyrrolopyrrole Derivatives with Exceptionally High Electron Affinities

Open-shell singlet biradicaloids are short-lived intermediates, but they exhibit fascinating properties for spinbased devices. Therefore, understanding the nature of their electronic structure and stability is critical for harnessing them in optoelectronic or spintronic devices. Toward this goal, we have synthesized a series of diketopyrrolopyrrole-based quinoidal molecules to investigate the c...

Asymmetric synthesis and cytotoxic activity of isomeric phytosphingosine derivatives.

New phytosphingosine analogues have been conceived, synthesised and their cytotoxicity in B16 murine melanoma cells tested. These compounds embed an isomeric substitution pattern resulting from a formal permutation of the C-2 and C-4 substituents along the aliphatic skeleton of the original sphingoid base. Five different stereoisomers have been accessed through regio- and stereocontrolled openi...

Asymmetric Synthesis of Modafinil and its Derivatives by using the Functionalized Silica-based Mesoporous MCM-41

Modafinil [2-[(diphenylmethyl)sulfinyl]acetamide] is used clinically in the treatment of narcolepsy and sleeping disorders. The synthesis of modafinil, begins with the reaction of benzhydrol and thioglycolic acid in trifluoroacetic acid to afford benzhydrylsulfinyl acetic acid. The reaction of acid with thionyl chloride in benzene followed by treatment with ammonium hydroxide gave acetamide...

Diketopyrrolopyrrole derivatives for efficient NiO-based dye-sensitized solar cells.

Two new diketopyrrolopyrrole (DPP) based sensitizers (DPP-Br, DPPCN2) and a novel dyad DPP-NDI (NDI = naphthalene diimide) were synthesized and investigated for use in NiO p-type dye-sensitized solar cells (p-DSCs). The simple push-pull DPP-CN2 gives a promising photoconversion efficiency (PCE) of 0.07% with the iodide/triiodide electrolyte while the PCE of the dyad reaches 0.18% with a cobalt ...
