A method for preparing an enantiomeric chromane, by asymmetrically hydrogenating a chromene compound in the presence of an Ir catalyst having a chiral ligand. The method includes the enantioselective preparation of enantiomeric equol. A preferred Ir catalyst has a chiral phosphineoxazoline ligand. Enantiomeric chromanes of high stereoselective purity can be obtained.

Method for enantioselective hydrogenation of chromenes

A method for synthesizing an oligonucleotide which comprises using a sulfurizing agent of general formula (I) for sulfurizing at least one phosphorus internucleotide linkage of a precursor of the oligonucleotide, wherein R is an aryl group or a heteroaryl group, which is bonded to the S-atom through an annular carbon atom; and Rand Rare independently organic residues, preferably a C1-C20 hydrocarbon residue. The method may further comprise purifying the oligonucleotide. Also included is a process for the synthesis of the sulfurizing agent. 

Method of using N-thio compounds for oligonucleotide synthesis

The present invention relates to a host material comprising a compound having two carbazole moieties which is suitable for blue-emitting OLEDs. Surprisingly, it has been found that when appropriate substituents are present in the carbazole structure, the solubility of the compounds can be improved without any adverse effect on the OLED performance. The present invention further relates to the use of the host materials and to an organic light emitting device comprising the host material.
