Abstract: The title compound (2) was prepared in high yield by catalytic transfer hydrogenation of the 6-nitro precursor (1), using hydrazine hydrate as the hydrogen source. Under the conditions employed, the ester groups remain unaffected. The new compound was fully characterised by elemental analysis, 1H-NMR, 13C-NMR, MS and HRMS data.

Abstract: A steroid with the dimeric structure, N,N-bis(3β-acetoxypregn-5(6)-en-20-on-16α-yl)hydroxylamine was synthesized in the base catalyzed reaction of 3β-acetoxypregn-5,16-dien-20-one with O-(trimethylsilyl)hydroxylamine. The structure of the product was determined by NMR (including 2D techniques), FAB MS, IR spectroscopy and elemental analysis.

Abstract: The title compound has been prepared from 1,5-dibromonaphthalene (obtained from 1,5-diaminonaphthalene) using Suzuki-Miyaura cross-coupling to 4-pyridylboronic acid. The crystal and molecular structure was determined by single-crystal X-ray diffraction.

Abstract: Diphenylmethane-based compounds bearing heterocyclic recognition groups, capable to act as hydrogen bonding sites were established to be powerful receptors for carbohydrates. In this paper, we describe the synthesis of a further representative of this class of compounds, containing four 1,8-naphthyridine groups as recognition units. The title compound has been characterized by elemental analysis, 1H-NMR, 13C-NMR and mass spectrometry.
