Hydrophilic diamine ligands for catalytic asymmetric hydrogenation of C=O bonds

Asymmetric hydrogenations of phenylglyoxylate methyl ester and of acetophenone with catalytic amounts of iridium complexes containing hydrophilic chiral C2-symmetric diamine ligands is reported. E.e. values of up to 68% are observed for complet

Practical and efficient synthesis of C2 symmetrical diamines with Zn / Me3SiCl

C2 symmetrical diamines are efficiently obtained by reductive coupling of imines with the couple Zn/Me3SiCl. This high yielding method is very practical and cheap for large scale preparation.

Isomerization of meso diamines into their C2 symmetrical d,l isomers

An efficient isomerization method is disclosed which allows the obtention of the useful d,l isomers of C2 symmetrical diamines, starting from their meso isomer.
