Statistical analysis of noncovalent interactions of anion groups in crystal structures. II. Hydrogen bonding of thiocyanate anions

Autor: L. Tchertanov, C. Pascard

Publikováno v: Acta Crystallographica Section B Structural Science. 52:685-690

The hydrogen-bond acceptor function of the thiocyanate anion is analyzed in 52 crystal structures retrieved from the Cambridge Crystallographic Database. All modes of hydrogen-bond coordination are represented: by the sulfur, by the nitrogen and by t

Absrrucr. New dicopper(1) knots have been synthesized as well as their face-to-face isomers. The knots range from 80 to 90-membered rings and their preparation yields depend crucially on structural parameters such as number of methylene fragments lin

Chirality directed self-assembly. Resolution of 2,5-diazabicyclo[2.2.2]octane-3,6-dione and crystal structures of its racemic and (−) enantiomeric forms

Autor: C. Pascard, Jacqueline Gabard, Gilles Dutruc-Rosset, Michèle Cesario, Michel Cheve, Jean-Marie Lehn, Marie-Josèphe Brienne, M. Leclercq

Publikováno v: Tetrahedron Letters. 35:8157-8160

The chiral bicyclic bis-lactam 1 has been resolved and the crystal structures of the racemate (±)-1 and of enantiomerically pure (−)-1 have been determined. They show that the chiral nature of the substance determines the supramolecular architectu

Endoperoxide diterpenes from Calceolaria purpurea

Autor: Marisa Piovano, M.Cristina Chamy, Michèle Cesario, C. Pascard, Juan A. Garbarino

Publikováno v: Phytochemistry. 34:1103-1106

Two new diterpenoids have been detected in Calceolaria purpurea and identified as 2α-malonyloxy- abieta-11 (12)-ene-9α,13α-endoperoxide, and 2α-malonyloxy-abieta-11(12)-ene-9β,13β-endoperoxide. The structure of the first terpenoid was determine
