  Structure–activity relationships of ustiloxin analogues

  摘要：

  Four novel ustiloxin D analogues were synthesized focusing on the size of the macrocyclic core, the stereochemistry at the bridgehead ether, and the enantiomer of ustiloxin D. All four were subjected to biological evaluation testing the inhibition of tubulin polymerization. Only 2,2-dimethyl-ustiloxin D retained any activity. (C) 2011 Elsevier Ltd. All rights reserved.

  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.

  The first total synthesis of the enantiomer of the indolizidine alkaloid, cyclizidine, was accomplished from readily available d-serine as the starting chiron. The relevant key reactions involve the stereocontrolled construction of the indolizidine ring system with the required functionality and further elaboration to install the cyclopropyl dienyl side chain. With this total synthesis, the absolute

  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 ustiloxins are a family of heterodetic cyclopeptides that have been isolated from the water extracts of false smut balls on the panicles of rice plants caused by the fungus Ustilaginoidea virens. A concise total synthesis of ustiloxin D has been achieved via an unprecedented ethynyl aziridine ring-opening of phenol derivatives. The longest linear sequence of the synthesis is 15 steps from commercially available compounds.
