A Convenient Route to 2-Hydroxy- and 2,15-Dihydroxyhexahelicene

Autor: Ivo Starý, Filip Teplý, Adrian Kollárovič, Zuzana Krausová, David Šaman, Daniel Luštinec, Irena G. Stará, Pavel Fiedler

Publikováno v: European Journal of Organic Chemistry. 2007:4244-4250

2-Hydroxy- and 2,15-dihydroxyhexahelicene were synthesised from simple benzene and naphthalene building blocks by intramolecular CoI- or Ni0-catalysed [2+2+2] cycloisomerisation of CH3O-substituted aromatic triynes. This approach avoids vexing photod

Synthesis of Methoxy Substituted Centrally Chiral Triynes as Precursors of Functionalised Nonracemic Helicene-Like Compounds

Autor: Josef Cvačka, Zuzana Krausová, Ivo Starý, David Šaman, Filip Teplý, Irena G. Stará, Petr Sehnal, Pavel Fiedler

Publikováno v: Collection of Czechoslovak Chemical Communications. 72:1499-1522

A modular synthesis of a series of methoxy substituted optically pure aromatic triynes (-)-(S)-5-9 and (-)-(R)-10 is presented. It relies on key operations such as substitution of benzylic bromine with an alkoxy group and aryl-alkyne coupling reactio

Publikováno v: Neurochemical Research. 25:1623-1627

Concentrations of neurosteroids may be influenced by some physiological or pathological factors. We investigated neuroactive steroids in the serum of women suffering from anxiety-depressive disorder treated with fluoxetine and in a control group, in
