5,5-Dialkyldipyrromethane as a precursor for the synthesis of calix[4]phyrins and pseudocorroles using MacDonald [2+2] condensations

Autor: Wim Dehaen, Suzanne Toppet, Czeslawa Orlewska, Wouter Maes

Publikováno v: Tetrahedron Letters. 46:6067-6070

The reaction of formylated dialkyldipyrromethanes with 5,5-dialkyl or 5-aryldipyrromethanes afforded meso-tetraalkyl or dialkylaryl-calix[4]phyrins, respectively. Templating with Ni(II) was needed to get these compounds in acceptable yields. From the

Abstract 1440: Endothelial And Cardiomyocyte Toxicity Of Endogenously Produced Nucleoside: 4-pyridone-3-carboxamide-1-β-d-riboside

Autor: Ewa M Slominska, Czeslawa Orlewska, Cesare M Terracciano, Ada H Yuen, Urszula Siedlecka, Magdi H Yacoub, Ryszard T Smolenski

Publikováno v: Circulation. 116

Our recent studies identified hitherto unknown, naturally occurring nucleotide: 4-pyridone-3-carboxamide-1-β-D-ribonucleoside triphosphate (4PYTP). This nucleotide was found to accumulate in the erythrocytes of patients with chronic renal failure, a

Synthesis of Calix[4]phyrins Derived from Dipyrroheptane

Autor: Czeslawa Orlewska, Suzanne Toppet, Wim Dehaen

Publikováno v: ChemInform. 36

Novel, highly lipophilic isomeric calix[4]phyrins were prepared by condensation of disubstituted dipyrromethane with an aldehyde.
