  tetrahydrofuran derivatives was developed via a phosphine-catalysed [3 + 2] cyclization reaction of aromatic aldehydes with 4-phenylbut-3-yn-2-one. This is the first example of intermolecular cyclization of ynones with benzaldehydes, which essentially benefited from the intramolecular hydrogen bonding. This new protocol features a broad substrate scope, mild reaction conditions, operational simplicity and easy scale-up

  Fluorinated derivatives of radicamine A and radicamine B have been synthesized from D-arabinose-derived cyclic nitrone. Structure–activity relationship studies showed that glycosidase inhibition of these fluorinated derivatives was significantly influenced by the position of the fluorine atom. C-7 or C-11 fluorination of the aromatic ring decreased α-glucosidase inhibition of the derivatives, whereas

• Regioselective synthesis of 6-substituted 2-hydroxybenzaldehyde: efficient synthesis of the immunomodulator tucaresol and related analogues
  作者：Boulos Zacharie、Giorgio Attardo、Nancy Barriault、Christopher Penney

  DOI：10.1039/a701102d

  日期：——

  Two new improved procedures have been developed for the preparation of the immunostimulant tucaresol 1 [4-(2-formyl-3-hydroxyphenoxymethyl)benzoic acid]. These approaches, which start from resorcinol or 2,6-dimethoxybenzaldehyde, are practical and therefore amenable to scale-up. In the case of the second approach, the multi-step synthesis reported in the literature has been reduced to three steps. Furthermore, unlike the reported method, our synthesis is versatile for the preparation of tucaresol analogues. The method is general and applicable for the preparation of 6-substituted 2-hydroxybenzaldehydes.

  已开发出两种改进的新方法用于制备免疫刺激剂图卡雷索1 [4-(2-甲醛-3-羟基苯氧甲基)苯甲酸]。这两种方法分别从间苯二酚或2,6-二甲氧基苯甲醛出发，具有实际可行性，因此适合放大规模生产。就第二种方法而言，文献中报道的多步骤合成已简化为三个步骤。此外，与报道的方法不同，我们的合成方法具有通用性，适用于制备图卡雷索类似物。该方法同样适用于制备6-取代的2-羟基苯甲醛。
