    • The present invention relates to a novel manufacturing process and novel intermediates useful in the synthesis of pharmaceutically active compound such as Aliskiren.The invention describes preparation of enantiomerically pure 8-aryloctanoic acid of formula I from a chiral compound of formula IV. Friedel-Crafts reaction of this compound of formula IV with a compound of formula III provides compound of formula II which is converted reductively in a few steps into the compound of formula V, a know intermediate in the synthesis of compound of formula I. According to the disclosed process, Aliskiren can be now prepared from commercial starting materials (Guajacol or 2-bromoanisole, cis- or trans-1,4-dichloro-2-butene and 4(S)-benzyl-3-isovaleroyl-oxazolidin-2-one) in less than 8 process steps.
