Journal ArticleDOI
Emergence of palladium(IV) chemistry in synthesis and catalysis.
TL;DR: The need to comprehensively review catalytic PdIV chemistry, particularly in organic synthesis, was identified, which draws on aspects from both inorganic (organometallic) and organic chemistry fields, and the historical background to organopalladium(IV) chemistry is detailed.
Journal ArticleDOI
An organometallic route to long helicenes
Petr Sehnal,Irena G. Stará,David Šaman,Miloš Tichý,Jiří Míšek,Josef Cvačka,Lubomír Rulíšek,Jana Vacek Chocholoušová,Jaroslav Vacek,Grzegorz Goryl,Marek Szymonski,Ivana Císařová,Ivo Starý +12 more
TL;DR: An organometallic approach to the derivatives of undecacyclic helicene is reported on, based on intramolecular [2 + 2 + 2] cycloisomerization of aromatic hexaynes under metal catalysis closing 6 new cycles of a helicene backbone in a single operation.
Journal ArticleDOI
Asymmetric Synthesis of [7]Helicene-Like Molecules†
Irena G. Stará,Zuzana Alexandrová,Filip Teplý,Petr Sehnal,Ivo Starý,David Šaman,Milos Budesínský,Josef Cvačka +7 more
TL;DR: A new approach to nonracemic [7]helicene-like molecules has been developed that can be controlled by the absolute configuration at the asymmetric center and by the presence of carbon substituents.
Journal ArticleDOI
On the origin of diastereoselectivity in [2 + 2 + 2] cycloisomerization of chiral triynes: controlling helicity of helicene-like compounds by thermodynamic factors.
Petr Sehnal,Zuzana Krausová,Filip Teplý,Irena G. Stará,Ivo Starý,Lubomír Rulíšek,David Šaman,Ivana Cisarova +7 more
TL;DR: Diastereoselective CoI-mediated [2 + 2 + 2] cycloisomerization of CH(3)O-substituted optically pure aromatic triynes to obtain nonracemic functionalized helicene-like compounds was studied.
Journal ArticleDOI
Helicene‐Based Phosphite Ligands in Asymmetric Transition‐Metal Catalysis: Exploring Rh‐Catalyzed Hydroformylation and Ir‐Catalyzed Allylic Amination
Zuzana Krausová,Petr Sehnal,Bojan P. Bondzic,Serghei Chercheja,Peter Eilbracht,Irena G. Stará,David Šaman,Ivo Starý +7 more
TL;DR: In this article, the first use of helicene-like ligands in asymmetric reactions, including hydroformylation and allylic amination, was presented. And the promising results indicate the potential of the helicene moieties as chiral inductors.
