The First Direct Synthesis of Corroles from Pyrrole.
The solvent-free, catalyst-free condensation of pyrrole and aldehydes provides an extremely facile synthetic pathway to novel corroles [Eq. (1); Ar=C6 F5 , 2,6-F2 C6 H3 , 2,6-Cl2 C6 H3 ]. The product… Expand
Solvent-Free Condensation of Pyrrole and Pentafluorobenzaldehyde: A Novel Synthetic Pathway to Corrole and Oligopyrromethenes
The solvent-free condensation of pyrrole and pentafluorobenzaldehyde (and to a lesser extent other electron-poor aldehydes as well) leads to a variety of products, of which three have been isolated… Expand
Erste direkte Synthese von Corrolen aus Pyrrol
Die losungsmittel- und katalysatorfreie Kondensation von Pyrrol und Aldehyden bietet einen auserst einfachen Zugang zu neuartigen Corrolen [Gl. (1); Ar = C6F5, 2,6-F2C6H3, 2,6-Cl2C6H3]. Das… Expand
First catalysis by corrole metal complexes: epoxidation, hydroxylation, and cyclopropanation
The first ever application of corroles shows that their metal complexes are good catalysts, almost as potent as the corresponding metalloporphyrins in the oxygenation of hydrocarbons by… Expand

Following the intriguing report about catalysis by corrole metal complexes, we present now the syntheses and characterization of the cobalt(III), rhodium(III), and iron(IV)… Expand
Metalloporphyrin catalyzed asymmetric cyclopropanation of olefins
Abstract Asymmetric cyclopropanation of styrene by an enantiopure carbenoid under catalysis by simple metalloporphyrins was found to be much more efficient and selective than the alternative… Expand
N‐substituierte Corrole: eine neue Klasse chiraler Liganden
A novel synthesis of protected glucose intermediates
The 1,2,4,6-Tetra-O-pivaloyl-D-gluco-pyranose 3 and 1,2,3,6-Tetra-O-pivaloyl-D-gluco-pyranose 4 have been prepared in one step from anhydrous glucose and pivaloyl chloride. These new intermediates… Expand
Stereoselective cyclopropanation with a sultam carbenoid
Abstract Stereoselective cyclopropanation of alkenes with the Oppolzer's sultam carbenoid was examined for the first time. The addition reaction proceeds in high yields on substituted alkenes and… Expand
Synthesis and utilization of saccharide intermediates.
A new method has been developed for preparation of partially pivaloylated saccharides in one step from readily available starting materials. These intermediates were used in the synthesis of… Expand
