  手性双环咪唑催化的酰基动力学动力学拆分合成手性邻苯二甲酰基酯

  摘要：

  利用手性双环咪唑有机催化剂并采用连续注射工艺，已开发出另一种途径，可通过对映选择性酰化作用（3-99％ee）动态动力学拆分3-羟基邻苯二酚来有效合成手性邻苯二甲酸酯基前药。计算研究表明，一般的基础催化机理不同于广泛接受的亲核催化机理。关键过渡态的结构分析表明，催化剂与底物之间的CH-π相互作用而不是先前考虑的阳离子/π-π相互作用是引起观察到的立体控制的主要因素。

  Aromatische Spirane, 21. Mitt: Darstellung von Methylphthalaldehyds�uren und ihren Ethylund Methylestern als Synthone f�r Synthesen von methylierten 2,2?-Spirobiindandionen

  摘要：

  The isomeric methyl phthalaldehydic acids 11 were obtained from phthalides 4 by bromation (NBS) to the 3-bromo derivatives 7 and subsequent hydrolysis with water. 4 in turn were accessible from dimethyl methyl benzoates 1 by dibromination with NBS and subsequent thermical cyclization to the bromo derivatives 3 which, on catalytic dehalogenation, afforded the phthalides 4. Reaction of 11 with methanol or ethanol gave the pseudo-esters 13 and 14, resp. Short treatment of 11 with diazomethane on the other hand yielded the methyl formyl benzoates 15b to 15e. Prolonged reaction (several hours) gave the oxiranyl compounds 17; in addition, the acetonyl derivatives 18 were also found, obviously formed by a double methylene insertion into 15. All reactions proceeded with good to excellent yields.
