  Synthesis and Biological Evaluation of 2-(Alkoxycarbonyl)-3-Anilinobenzo[b]thiophenes and Thieno[2,3-b]pyridines as New Potent Anticancer Agents

  摘要：

  Two new series of inhibitors of tubulin polymerization based on the 2-(alkoxycarbonyl)-3-(3',4',5'-trimethoxyanilino)benzo[b]thiophene and thieno[2,3-b]pyridine molecular skeletons were synthesized and evaluated for antiproliferative activity on a panel of cancer cell lines, inhibition of tubulin polymerization, cell cycle effects, and in vivo potency. Antiproliferative activity was strongly dependent on the position of the methyl group on the benzene portion of the benzo[b]thiophene nucleus, with the greatest activity observed when the methyl was located at the C-6 position. Also, in the smaller thieno[2,3-b]pyridine series, the introduction of the methyl group at the C-6 position resulted in improvement of antiproliferative activity to the nanomolar level. The most active compounds (4i and 4n) did not induce cell death in normal human lymphocytes, suggesting that the compounds may be selective against cancer cells. Compound 4i significantly inhibited in vivo the growth of a syngeneic hepatocellular carcinoma in Balb/c mice.

• Supramolecular Control of Selectivity in Hydroformylation of Vinyl Arenes: Easy Access to Valuable β-Aldehyde Intermediates

  flow! A rationally designed regioselective hydroformylation catalyst, [Rh/L], in which noncovalent ligand–substrate interactions allow the unprecedented reversal of selectivity from the typical α‐aldehyde to the otherwise unfavored product β‐aldehyde, is reported. This catalytic system opens up novel and sustainable synthetic pathways to important intermediates for the fine‐chemicals industry.

  Ullmann dimerization of substituted methyl 3-X-1-benzothiophene-2-carboxylates 1-7 (X = Cl, Br) gave rise to the corresponding dimeric 3,3'-bi(1-benzothiophene) esters 8-13. Resolution of the title acid 20 by fractional crystallization of its mono- and bisquininium salt afforded pure (R)- and (S)-enantiomers, the optical purity and absolute configuration of which was confirmed by CD spectrometry and by X-ray crystallography. Ullmann dimerization of chiral oxazolines 23 and 24 derived from 2 proceeded without any diastereodifferentiation. Reduction of (R)- and (S)-20 afforded the corresponding (R)- and (S)-diols 29, which served as chiral ligands in a model enantioselective reduction of acetophenone. (R)- and (S)-1-phenylethan-1-ol were formed in 28 and 29% e.e., respectively.

  用替代基取代的甲基3-X-1-苯并噻吩-2-羧酸甲酯（X = Cl，Br）进行Ullmann二聚化反应，得到相应的二聯苯并噻吩酯（8-13）。通过对标题酸20进行单酰铵盐和双酰铵盐的分馏结晶，得到纯度较高的（R）-和（S）-对映体，其光学纯度和绝对构型通过CD光谱和X射线晶体学得到确认。从2衍生的手性噁唑啉23和24的Ullmann二聚化反应在没有差向异构化的情况下进行。对（R）-和（S）-20的还原得到相应的（R）-和（S）-二醇29，它们在模型对苯甲酮的对映选择性还原中作为手性配体。分别形成28%和29%的（R）-和（S）-1-苯基乙醇。
