    Green Method for the Synthesis of Chromeno[2,3-c]pyrazol-4(1H)-ones through Ionic Liquid Promoted Directed Annulation of 5-(Aryloxy)-1H-pyrazole-4-carbaldehydes in Aqueous Media
    摘要:
    The first classical heterocyclic ionic liquid (IL) promoted C-H bond oxidant cross-doupling,reaction for the intramolecular annulation of 5-(aryloxy)-1H-pyrazole-4-carbal- dehydes to chromeno[2,37c]pyrazol-4(1H)-ones has been disclosed The promoter 1,3-dibutyl-1H-benzo[d]fl 2 3]- triazol-34-ium bromide can be easily recycled reused with the same efficacies for at least five cycles in aqueous medium The strategy works smoothly and provides applicable protocol to construct a Wide range of products.

    A straightforward, two-step synthesis of fluoro substituted chromeno[2,3-c]pyrazol- and [1]benzothieno[2′,3′:5,6]pyrano[2,3-c]pyrazol-4(1H)-ones, respectively, is presented. Hence, treatment of 1-substituted or 1,3-disubstituted 2-pyrazolin-5-ones with fluoro substituted 2-fluorobenzoyl chlorides or 3-chloro-6-fluoro-1-benzothiophene-2-carbonyl chloride using calcium hydroxide in refluxing 1,4-dioxane

  • Copper-Catalyzed Tandem O-Arylation–Oxidative Cross Coupling: Synthesis of Chromone Fused Pyrazoles
    作者:Owk Obulesu、K. Harish Babu、Jagadeesh Babu Nanubolu、Surisetti Suresh

    日期:2017.3.17
    Intermolecular tandem copper-catalyzed O-arylation-oxidative acylation (cross dehydrogenative coupling-CDC) has been developed under air as an oxidant. The reaction between 2,4-dihydro-3H-pyrazol-3-ones and ortho-halo aryl carboxaldehydes furnished the corresponding chromone fused pyrazoles, in a straightforward manner. The synthetic utility of the presented tandem catalysis has been demonstrated with the synthesis of an A(2)-subtype selective adenosine receptor antagonist in only two steps.[GRAPHICS]
