  3-Aminopyridazine derivatives with atypical antidepressant, serotonergic and dopaminergic activities

  摘要：

  Minaprine [3-[(beta-morpholinoethyl)amino]-4-methyl-6-phenylpyridazine dihydrochloride] is active in most animal models of depression and exhibits in vivo a dual dopaminomimetic and serotoninomimetic activity profile. In an attempt to dissociate these two effects and to characterize the responsible structural requirements, a series of 47 diversely substituted analogues of minaprine were synthesized and tested for their potential antidepressant, serotonergic, and dopaminergic activities. The structure-activity relationships show that dopaminergic and serotonergic activities can be dissociated. Serotonergic activity appears to be correlated mainly with the substituent in the 4-position of the pyridazine ring whereas the dopaminergic activity appears to be dependent on the presence, or in the formation, of a para-hydroxylated aryl ring in the 6-position of the pyridazine ring.

  Making use of CO: An improved efficient synthesis of 5‐aryl‐3‐alkylidenefuran‐2‐ones has been developed (see scheme). Starting from readily available (hetero)aryl bromides or aryl triflates and alkynes, furanones were produced in good yields through a double carbonylation process. To illustrate the generality of the method more than 25 furanone derivatives were synthesized, including the permethylated

  DOI：10.1039/c7ob01570d

  日期：——

  A new, cis-selective, approach for the synthesis of bicyclic δ-lactones bearing a fused cyclohex-2-en-1-one moiety is described. The strategy utilizes a cascade reactivity of cyclic 1,3-diketones and 3-arylidenefuran-2(3H)-ones with the butenolide-ring-opening reaction enabling the construction of the δ-lactone framework. It benefits from broad scope, high enantioselectivity and excellent cis-diastereoselectivity
