Abstract
Official abstract text for this publication.
A process for the preparation of a chiral compound, in particular posaconazole, wherein the process comprises mixing and reacting the compounds of formula (I) Y 3 —NH 2 ; of formula (IIa) 0=C═N—Y 0 and/or of formula (IIb) and of formula (III) in a solvent in any order to obtain a reaction mixture containing a chiral compound of formula (IV) and/or formula (V).
First claim
Opening claim text (preview).
The invention claimed is: 1. An optionally crystalline chiral compound of formula (IVa) or a salt thereof, wherein R 1 is an alkyl residue having from 1 to 6 carbon atoms and wherein —R is —H or the hydroxyl protecting group —SiR a R b R c , where R a , R b and R c are the same or different and selected from the group consisting of optionally suitably substituted a…
