Abstract: A catalytic process for the preparation of optically active compounds and their conversion thereafter to desired drug substances. In particular, the process relates to the preparation of (S)-3-(1-Dimethylamino-ethyl)-phenol using asymmetric catalytic reduction and transfer hydrogenation, thereby providing an improved route to forming drug substances such as rivastigimine and rivastigimine hydrogen tartrate.

Abstract: The invention provides a novel process, novel process steps and novel intermediates useful in the synthesis of pharmaceutically active compounds, especially renin inhibitors, such as Allskiren. Inter alia, the invention provides a process for the manufacture of a compound of the formula III, wherein R, R1, R2, R3 and PG are as defined in the specification, or a salt thereof. The manufacture comprises (preferably consists of) reacting a compound of the formula I, with a reagent able to transform hydroxy into X where X is for example a leaving group.

Abstract: A novel method has been found to produce 2,2?-anhydro-1-(?-L-arabinofuranosyl)thymine as a novel useful intermediate compound. A novel method has been further found to produce thymidine from 2,2?-anhydro-1-(?-L-arabinofuranosyl)thymine. According to these methods, synthesis of various L-nucleic acid derivatives, synthesis of which has been difficult till now, is possible.
