different from the ones observed with the corresponding Grignardreagents, which allows, in several cases, the preparation of both enantiomers of an amine from the same imine substrate. When mixed triorganozincates are used, one can take advantage of the slow transfer rate of the methyl group to use it as a non-transferable one. Both aromatic and aliphatic aldimines, as well as activated ketimines, are good
The present invention relates to compounds useful in therapy, in particular in the treatment of psychosis, to compositions comprising said compounds, and to methods of treating diseases comprising the administration of said compounds.

Commercially available transaminases are valuable tools for the synthesis of chiral amine building blocks and are very accessible to the synthetic chemistry community. We demonstrate that selected commercially available enzymes from Codexis’ transaminase collection can accept and aminate bulky-bulky ketones in up to 99 % ee.
