  A new series of 4,5-dihydro-1H-thiochromeno[4,3-d]pyrimidine derivatives have been designed and synthesized. The antitumor activities of the target compounds have been evaluated in vitro against two human cancer cell lines including A549 (human alveolar adenocarcinoma cell) and H460 (human lung cancer) by MTT assay. Most of the target compounds exhibited significant antitumor activities against A549 and H460 cancer cell lines. The most potent compound 4-(benzo[d][1,3]dioxol-5-yl)-8,9-difluoro-2-(4-methylpiperazin-1-yl)-4,5-dihydro-1H-thiochromeno[4,3-d]pyrimidine (CH05) (IC50 = 0.44 μM, 3.07 μM) was 2.0 and 8.4 times more active than gefitinib (IC50 = 0.89 μM, 16.81 μM) against A549 and H460 cell lines, respectively.

  As epoxy functional group has high anticancer activity, α,β‐epoxyketones were designed and synthesized as new anticancer agents, and their structures were confirmed by UV, 1H NMR, IR, MS technigeces and elemental analysis. Their in vitro anticancer activities were evaluated by MTT method and the results showed that the compound 4c exhibited good activity with IC50 of 17.8, 22.0 and 24.1 µg/mL against

  作者：Liu Xiao-Ming、Yang Geng-Liang、Song Ya-Li、Liu Jie-Jie、Wang Yang、Zhang Dong- Nuan

  A series of novel (E)-2,3-dihydro-3-[(phenylamino)methylene]-4H-1-benzothiopyran-4-ones has been synthesized by using 2,3-dihydro-4H-1-benzothiopyran-4-ones as the starting material. The structures of the new compounds are characterized by UV-vis, IR, HRMS, 1H NMR, and 13C NMR. 2D NMR spectroscopic studies revealed that at room temperature, these compounds rather exist in the keto-enamine than in the Schiff base form. The synthesized compounds were evaluated against two species of fungi in vitro by agar double dilution method. The results of antifungal screening revealed that the MIC value of (E)-8-chloro-2,3-dihydro-3-[(4-nitrophenylamino)methylene]-4H-1-benzothiopyran-4-one (4j) against Candida albicans is 32 μg·ml-1 while the control Fluconazole is 64 μg·ml-1.

  日期：2016.10.7

  A highly efficient asymmetric synthesis of chiral thioflavanones is developed via conjugate addition of arylzinc reagents to thiochromones using Rh(COD)Cl2/(R)-3,4,5-MeO-MeOBIPHEP catalyst. This method overcomes catalyst poisoning and substrate inertness and affords a series of chiral thioflavanones (2-arylthiochroman-4-ones) in good yields (up to 91% yield) with excellent ee values (up to 97% ee)

  The enantioselective incorporation of alkyl groups in thiochromones was realized for the first time by a Cu/(R,S)-PPF-P t Bu2-catalyzed conjugate addition of Grignard reagents to thiochromones. With this method, a series of 2-methylthiochromanones were obtained in good yields (up to 96% yield) with moderate-to-good ee values (up to 87% ee). The established method expedites the synthesis of a large
