A method for the parallel solid-phase synthesis (SPS) of iodinated analogues of Sanofi-Aventis' type 1 cannabinoid (CB1) receptor inverse agonist rimonabant (acomplia) has been developed. The method allows the synthesis of a range of C3 amide/hydrazide derivatives from a resin-bound C3 ester precursor. The C-Ge linkage to the Hypogel-200 resin is stable to the diversification conditions but allows ipso-iododegermylative cleavage using NaI/NCS even for the products containing the oxidatively labile hydrazide moiety.
