  Reactions of carbon nucleophiles with 2,2,3-trisubstituted ethynylaziridines

  摘要：

  Carbon nucleophiles were used to open a 2,2,3-trisubstituted ethynylaziridine. A cyanide nucleophile opened the ring at the more substituted carbon, proceeding regioselectively with inversion of configuration. In an attempt to expand upon the scope of the reaction, Normant cuprates were reacted with a 2,2,3-trisubstituted ethynylaziridine. This reaction produced chiral allenes via an anti-S(N)2' pathway. X-ray analysis of a derivative allowed the absolute stereochemistry of the anti-allenes to be assigned as P. Published by Elsevier Ltd.

  synthetically challenging chiral tertiary alkyl-aryl ether linkage. The first total synthesis of ustiloxin D was achieved in 31 linear steps using an S(N)Ar reaction. An NOE study of this synthetic product showed that ustiloxin D existed as a single atropisomer. Subsequently, highly concise and convergent syntheses of ustiloxins D and F were developed by utilizing a newly discovered ethynyl aziridine ring-opening

  Ustiloxins AF 是抗有丝分裂杂环肽，含有 13 元环状核心结构，具有合成上具有挑战性的手性叔烷基芳基醚键。使用 S(N)Ar 反应，通过 31 个线性步骤实现了 ustiloxin D 的首次全合成。该合成产品的 NOE 研究表明乌司洛辛 D 作为单一阻转异构体存在。随后，利用新发现的乙炔基氮丙啶开环反应，以 15 个步骤的最长线性序列开发了乌斯蒂洛辛 D 和 F 的高度简洁和收敛的合成方法。该方法进一步优化以实现更好的大环内酰胺化策略。通过第二代制备了乌斯蒂洛辛D、F和8个类似物（14-MeO-乌斯蒂洛辛D、4个C-6位氨基酸残基不同的类似物、以及3个(9R,10S)-表乌斯蒂洛辛类似物）路线。对这些化合物作为微管蛋白聚合抑制剂的评估表明，C-6 位的变化在一定程度上是可以容忍的。相反，C-9 甲氨基的 S 构型和游离酚羟基对于抑制微管蛋白聚合至关重要。

  formation of these hindered ethers has been investigated using a variety of functionalized aziridines and phenols to determine the scope of the reaction. Other nucleophiles, such as thiolate, azide, and chloride, have also been examined to encompass the synthesis of a broader range of functionalities. This aziridine ring opening reaction manifold has demonstrated utility in assembling: beta-substituted-alpha-amino

  The total synthesis of ustiloxin D, a highly potent inhibitor of microtubule assembly, has been achieved. Notable features are the use of nucleophilic aromatic substitution (SNAr) for the construction of a chiral tertiary alkyl-aryl ether linkage, Sharpless asymmetric aminohydroxylation for the formation of the beta-hydroxytyrosine moiety, macrolactamization, and regioselective methylation.

  日期：1995.7

  A strategy for the preparation of 4,4-disubstituted-3-amino-2-azetidinones which are useful intermediates for the synthesis of analogues of monosulfactam Tigemonam, was developed. It employs D-serine as chiral starting material and involves, as key steps, the diastereoselective addition of organometal compounds to ketones 9 and the stereospecific cyclization of tertiary alcohols 7 to the beta-lactams 6.
