Abstract

The synthesis of aliskiren intermediates was accomplished by attaching the 3,4-dialkoxyphenyl unit to precursor C-8 lactone-carboxylic acid derivatives using organometallic reagents. Totally different reactivities of the lactone-carboxylic acid chloride substrate towards organomagnesium and organoboron reagents were observed.
