  Rigid Molecular Architectures That Comprise a 1,3,5-Trisubstituted Benzene Core and Three Oligoaryleneethynylene Arms:  Light-Emitting Characteristics and π Conjugation between the Arms

  摘要：

  In view of increasing interest in light-emitting materials, we have investigated the light-emitting characteristics and occurrence of conjugation between arms of star-shaped rigid molecules that comprise a 1,3,5-triethynylbenzene core and methoxy group-substituted oligo(p-phenylethynylene) arms. Consequently, we achieved the ultimate goal (Phif approximately 1.0, log epsilon > 5) for organic molecules with respect to light-emitting ability by creating very intense violet-blue (8, Phif = 0.97, log epsilon = 5.11) and blue (9, Phif = 0.98, log epsilon = 5.29) bright light-emitters. Also, pi conjugation was found to occur between the arms of 9 despite the meta-substituted system. We found a linear relationship of kr (with positive slope) and kd (with negative slope) with the number of dimethoxyphenyleneethynylene units for MMPT (4, 6, 8) and DMPT (5, 7, 9) homologues and the contrasting solvent effect on lambdaem of 8 and 9. It is also interesting that lambdaabs, epsilon, lambdaem, and Phif of 9 are greater than those of the corresponding banana- and rod-shaped molecules.

  shown that 1,3-propanediol acts both as a participant and solvent to achieve regioselective cyclization and carbonyl site oxygen migration. Significantly, the total synthesis of drug molecules efloxate 6 and flavodilol 7 and bioactive molecules, such as 8 and MN-64, further demonstrates the efficacy and synthetic potential of this method. Moreover, most established flavonoid derivatives are found to have

  开发了一种以β-苯氧基炔酮为原料，以湿1,3-丙二醇为反应介质，在不使用任何金属催化剂、碱、酸或添加剂的情况下，绿色、高效、高区域选择性合成黄酮类化合物及其衍生物的方法。该反应表现出高水平的功能耐受性和广泛的底物范围，操作简单，原子经济性高。此外，机制研究表明，1,3-丙二醇既作为参与者又作为溶剂，实现区域选择性环化和羰基位点氧迁移。值得注意的是，药物分子efloxate 6和flavodilol 7以及生物活性分子8和MN-64的全合成进一步证明了该方法的功效和合成潜力。此外，大多数已建立的黄酮类衍生物都具有很强的抗炎活性，其中2d表现出更好的效果，IC 50 值较低，为5.67 μg mL −1 。

• Palladium-Catalyzed Cyclization of <i>o</i>-Alkynylphenols with Allyl Carbonates. A Regioselective Synthesis of 2-Substituted-3-allylbenzo[<i>b</i>]furans

  2-Substituted-3-allylbenzo[b]furans 3 can be prepared from o-alkynylphenols 1 and allyl carbonates 2 through a palladium-catalyzed O-allylation/cyclization sequence. Two basic procedures have been developed: a stepwise method based on the isolation of O-allyl derivatives 4 and their subsequent cyclization to 3 (procedure A) and a one-pot reaction omitting the isolation of 4 (procedure B). The cyclization of 4 in the presence of the electron-rich sterically-encumbered ligand tris(2,4,6-trimethoxyphenyl)phosphine (ttmpp)exhibits remarkable regioselectivity in that 3-allylbenzofurans in which the benzofuryl unit is bound to the less substituted allyl terminus are formed almost exclusively. Some loss of the stereochemistry of the carbon-carbon double bond is observed.
