  Studies directed towards the synthesis of antascomicin A: stereoselective synthesis of the C22–C34 fragment of the molecule

  摘要：

  A stereoselective synthesis of the C22-C34 fragment of the non-immunosuppressive immunophilin-binding natural product, antascomicin A was achieved using D-quinic acid as the starting material and highly stereoselective aldol reactions were employed, as key steps, to build the remaining stereocentres at C23, C26 and C27.

  Carreira acetylide addition. Further routine steps led to the sulfones 29 and 45, respectively. After merging them with 2‐bromobenzaldehyde 9 in a Julia–Kocienski reaction, metalation, carboxylation, and protecting‐group manipulations gave the seco acids 35 and 49. By means of lactonization under Mitsunobu (alcohol activation) or Trost–Kita conditions (carboxyl activation), all four possible macrocyclic ketone

  通过有机合成用丙酸酯代替乙酸盐，制备了一系列具有烯丙基甲基的玉米赤霉烯酮类似物。为了合成类似物的脂肪族区域，我们使用了不对称烷基化反应生成了戊烯醇衍生物16和ent - 16。通过硼氢化反应，确保了相应的醛。通过加入Carreira乙炔化物将它们与2-戊炔醇衍生物23偶联。进一步的常规步骤分别导致了砜29和45。将它们与2-溴苯甲醛9合并后在一个朱莉娅- Kocienski所反应，金属化，羧化，和保护基团的操作，得到开环酸35和49。通过在Mitsunobu（酒精活化）或Trost-Kita条件（羧基活化）下进行内酯化，可以得到所有四种可能的大环酮立体异构体。总之，考虑各种保护基团的装饰品，获得和细胞毒性（L929小鼠成纤维细胞系）测试16点的类似物。而大多数类似物比玉米赤霉烯酮活性较低（IC 50 = 9.4μ中号），间苯二酚衍生物是可比的，用一种立体异构体（40b中）为稍微更活性（IC

• Asymmetric synthesis of a 12-membered macrolactone core and a 6-epi analogue of amphidinolide W from 4-pentenoic acid

  日期：2012.8

  A flexible and efficient asymmetric route to the synthesis of a 12-membered macrolactone core and a 6-epi analogue of amphidinolide W has been accomplished from commercially available 4-pentenoic acid. The successful generation of stereocenters was achieved by utilizing an Evans' chiral auxiliary-based alkylation and aldol reaction. Other key reactions such as a Julia-Kocienski olefination, Kita's macrolactonization, ring closing metathesis (RCM) reaction, and Yamaguchi's esterification were significant for the construction of the macrolactone cores.
