  • DBU-mediated regioselective intramolecular cyclization/dehydration of ortho diketo phenoxyethers: a synthesis of 2,3-substituted γ-benzopyranones
    作者:Sofia Bensulong、Jutatip Boonsombat、Somsak Ruchirawat
    DOI:10.1016/j.tet.2013.07.104
    日期:2013.11
    The regioselective cyclization/dehydration sequence of ortho diketo phenoxyethers induced by DBU has been explored. The results demonstrated a high degree of selectivity with preference for 6-exo-trig cyclization leading to the formation of gamma-benzopyranone derivatives in good yield. (C) 2013 Elsevier Ltd.

  • Structure−Activity Relationships in 1,4-Benzodioxan-Related Compounds. 6. Role of the Dioxane Unit on Selectivity for α<sub>1</sub>-Adrenoreceptor Subtypes
    作者:Wilma Quaglia、Maria Pigini、Alessandro Piergentili、Mario Giannella、Gabriella Marucci、Elena Poggesi、Amedeo Leonardi、Carlo Melchiorre

    WB 4101-related benzodioxans 3-9 were synthesized, and their biological profiles at alpha(1)-adrenoreceptor subtypes and 5-HT1A serotoninergic receptors were assessed by binding assays in CHO and HeLa cells membranes expressing the human cloned receptors. Furthermore, receptor selectivity of selected benzodioxan derivatives was further determined in functional experiments in isolated rat vas deferens ((alpha(1A)) and aorta (alpha(1D)) and guinea pig spleen (alpha(1B)), in additional receptor binding assays in rat cortex membranes containing alpha(2)-adrenoreceptors and 5-HT2 serotoninergic receptors, and in rat striatum membranes containing D-2 dopaminergic receptors. An analysis of the results of receptor binding experiments for benzodioxan-modified derivatives 3-9 showed high affinity and selectivity toward the alpha(1a)-adrenoreceptor subtype for compounds 3-5 and 7 and a reversed selectivity profile for 9, which was a selective aid antagonist. Furthermore, the majority of structural modifications performed on the prototype 1 (WB 4101) led to a marked decrease in the affinity for 5-HT1A serotoninergic receptors, which may have relevance in the design of selective alpha(1A)-adrenoreceptor antagonists. The exception to these findings was the chromene derivative 8, which exhibited a 5-HT1A partial agonist profile.
