Treatment of 7-(4-benzylphthalazin- 1-ylamino)-4-(p-methoxyphenyl)-4H-chromene-3-carbonitrile (9a) with triethyl orthoformate/Ac2O afforded ethoxymethyleneamino derivative 11. Condensation of 9a with DMFDMA/xylene gave chromenopyrimidine derivative 13, while treatment of 9a with Ac2O afforded the N-acetylimino derivative 14.

Quinazoline, quinoxaline and phthalazine are nitrogen containing heterocyclic aromatic molecules which belong to the class diazanaphthalenes. These isomers have low-lying n pi(star) and naphthalene-like pi pi(star) states that interact via spin-orbit coupling. In this contribution, we study their structure and electronic states by means of a coupled-cluster method. The computed properties are compared to those of cinnoline which were obtained in our previous study [Etinski et al., Phys. Chem. Chem. Phys., 2014, 16, 4740]. The excited state features of these isomers are dependent on the position of the nitrogen atoms. We find that quinazoline and quinoxaline exhibit similarities in the ordering and character of the excited states. In contrast, a marked difference in the electronic and geometric structures of the lowest excited triplet states of cinnoline and phthalazine is noticed, although both are orthodiazanaphthalenes. Our findings suggest that the S-1 (sic) T-1 channel is responsible for the rapid intersystem crossing in quinazoline and quinoxaline, whereas the S-1 (sic) T-2 pathway is active in phthalazine.

Four series of [1,2,4]triazolo[3,4-a]phthalazine and tetrazolo[5,1-a]phthalazine derivatives bearing substituted piperazine moieties were synthesized and evaluated for their positive inotropic activity by measuring the left atrium stroke volume in isolated rabbit-heart preparations. Several compounds were developed and showed favorable activities compared to the standard drug milrinone, with (4-([1,2,4]triazolo[3,4-a]phthalazin-6-yl) piperazin-1-yl)(p-tolyl) methanone (5g) being identified as the most potent with an increased stroke volume of 19.15 +/- 0.22% (milrinone: 2.46 +/- 0.07%) at a concentration of 3 x 10(-5) M. A preliminary study of mechanism of action revealed that 5g displayed its positive inotropic effect may be related to the PDE-cAMP-PKA signaling pathway. Compounds exhibiting inotropic effects were also evaluated in terms of the chronotropic effects. (c) 2014 Elsevier Ltd. All rights reserved.
