Synthesis and structure-affinity relationships of novel spirocyclic σ receptor ligands with furopyrazole structure

The synthesis of novel spirocyclic σ receptor ligands with high affinity is described. The cyclization of the hydroxy acetal 8, which represents a key step in the synthesis of the spirocyclic compounds 3, was supported by theoretical considerations. The a

Spiro-pyrano-pyrazole derivatives

The present invention relates to compounds of formula (I) having pharmacological activity towards the sigma (σ) receptor, and more particularly to some spiro-pyrano-pyrazole derivatives, to processes of preparation of such compounds, to pharmaceutical com
