description	The present invention relates to compounds useful as pharmaceutical intermediates, to processes for preparing the intermediates, to intermediates used in the processes, and to the use of the intermediates in the preparation of pharmaceuticals. In particular, the present invention concerns enantiomerically pure optionally substituted 2-(1-hydroxy-alkyl)-chromen-4-one derivatives represented by formula (IA) and (IB), processes for preparing the alcohol derivatives and their use in preparing pharmaceuticals.
