Our previous structure-affinity relationship study had considered the enantiomers of the naphthodioxane, tetrahydronaphthodioxane, and 2-methoxy-1-naphthoxy analogues ( compounds 1, 3, and 2, respectively) of 2-(2,6-dimethoxyphenoxyethylaminomethyl)-1,4-benzodioxane, the well-known alpha(1)-adrenoceptor (alpha(1)-AR) antagonist WB4101, showing that such modifications significantly modulate the affinity and selectivity profile for alpha(1)-AR subtypes and 5-HT1A receptor. Here, we extend investigations to antagonist activity enclosing new enantiomeric pairs, namely those of the methoxytetrahydronaphthoxy and methoxybiphenyloxy WB4101 analogues (4 and 5-7, respectively) and of a double- modified WB4101 derivative ( 8) resulting from hybridization between 2 and 3. We found that (S)-2 is a very potent (pA(2) 10.68) and moderately selective alpha(1D)-AR antagonist and the hybrid (S)-8 is a potent (pA(2) 7.98) and highly selective alpha(1A)-AR antagonist. Both of these compounds and (S)-WB4101 seem to act as inverse agonists in a vascular model. The results, which generally validate the logic we followed in designing these eight compounds, are acceptably rationalized by comparative SAR analysis of binding and functional affinities.

A microwave-assisted, base-promoted, tandem cyclization reaction strategy has been developed for the synthesis of cyclohepta[b]chromones and spiro cyclohepta[b]chromones. Readily accessible γ-alkynyl-1,3-diketones undergo intramolecular cyclization and 7-endo-trig carbocyclization to afford various cycloheptane-annelated chromones in one-potreactions. This metal-free protocol also led to the generation
