A similar rationale explains the formation of dibenzothiophene from 7 and thiophene, the four monomethylthianaphthenes 22-25 from 5 and cyclopentadiene, 5,6-dimethylthianaphthene (150 from 5 and 2,3-dimethylbutadiene, and a mixture of hydroxythianaphthenes ( 1 9 ) from 5 and furan. The latter reaction also produces a mixture

  Br-atom or a hydroxymethyl moiety in 2-position were less tolerated by the GluN2B receptor. Very similar relationships between the structure and GluN2B affinity and structure and σ affinity, in particular σ2 affinity, were detected. A slight preference for the ifenprodil binding site of GluN2B receptors over σ1 and σ2 receptors was found for methylamines 11c (≈2-fold) and 11d (≈1.5-2-fold) as well as for
