Synthesis of E-homoallylic alcohols, γ-hydroxyketones,and cyclopropyl ketones from 3-diphenylphosphinoyl (Ph2PO) propanols by acyl transfer

Carboxyl transfer (O→C) on 3-Ph₂PO propyl esters (9) gives an intermediate (10) from which the Ph₂PO group may be removed by the Horner-Wittig reaction or by Ph₂PO transfer (C→O) to give the title compounds.
