A novel procedure for synthesis of bivalent neurotransmitter ligands was developed by reacting O-benzyl protected N-nosylated dopamine and serotonin with alkyl- or PEG-linked diols under Fukuyama-Mitsunobu conditions in the presence of DIAD/PPh3 generating three different bivalent neurotransmitter ligands in a one-pot reaction. The methodology establishes a facile route towards bivalent neurotransmitter ligands, and libraries of in total 40 symmetrical and non-symmetrical bivalent and monovalent dopamine and serotonin compounds linked through alkyl or PEG spacers of varying length were prepared. Interestingly, attempted synthesis of an O-tert-butyl analogue of the N-nosylated serotonin precursor resulted in unexpected tert-butylations at the 1-, 2- and 6-positions of the indole skeleton. We found that upscaling of selected bivalent serotonin ligands was most efficiently performed via N,O-bis-nosyl-serotonin since global de-nosylation was carried out as a final step after Fukuyama-Mitsunobu dimerization.
