Herein, the synthesis and pharmacological evaluation of thiophene bioisosteres of the highly potent spirocyclic benzopyran 1 are detailed. The synthesis of 1-benzyl-6?-methoxy-6?,7?- dihydrospiro[piperidine-4,4?-thieno[3.2-c]pyran] (2a) was performed starting with 3-bromothiophene (3). After introduction of the acetaldehyde substructure (7), halogen metal exchange, addition of 1-benzylpiperidin-4-one, and cyclization led to the spirocyclic thienopyran 2a. The removal of the benzyl group afforded the secondary amine 2f, which was substituted with various residues. With respect to sigma1 affinity the N-benzyl derivative 2a, the N-cyclohexylmethyl derivative 2d, and the N-p-fluorobenzyl derivative 2i represent the most potent compounds of this series binding with Ki values of 0.32, 0.29, and 0.62 nM, respectively. Electronic properties of the substituents have only little impact on sigma1 affinity. The most potent sigma1 ligands display high selectivity against sigma2, 5-HT1A, 5-HT6, 5-HT7, alpha1A, alpha2, and NMDA receptors. The activity of 2a in the mouse capsaicin assay seems to indicate sigma1 antagonistic activity.
