  3-Unsubstituted 1,5-Diaryl-2,4-pentanediones and -4-methoxy-2-pentanones:  Synthesis via Corresponding 3-Hydroxy Ketones Generated from 2-Isoxazolines

  摘要：

  Aryl acetaldoximes are reacted with allylarenes in the presence of sodium hypochlorite to give 3,5-bis(arylmethyl)-2-isoxazolines which are then converted to 1,5-diaryl-4-hydroxy-2-pentanones by a reductive hydrogenation in the presence of water. These intermediate aldols can then be either oxidized with Corey-Kim reagent to stable dimethylsulfonium 1-(arylacetyl)-2-oxo-3-arylpropylides followed by zinc-acetic acid reduction to give 1,5-diaryl-2,4-pentanediones, or converted to 1,5-diaryl-4-methoxy-2-pentanones by refluxing in methanol in the presence of hydrochloric acid. A detailed study of this general route is reported here.

• One-pot enantioselective synthesis of (S)-spirobrassinin and non-natural (S)-methylspirobrassinin from amino acids using a turnip enzyme

  Abstract The enantioselective synthesis of (S)-(−)-spirobrassinin, which features a unique sulfur-containing spirooxindole skeleton, was achieved by focusing on the phytoalexin generation in Brassicaceae plants. Specifically, (S)-(−)-spirobrassinin was obtained in a one-pot fashion from l-tryptophan through a reaction involving S-spirocyclization with various turnip enzymes and constituents, i.e.,

• Homologation of Aryl Aldehydes Using Nitromethane as a C1 Source Enabled by Nitrogen-Doped Carbon-Supported Palladium Catalysts

  Homologation of aryl aldehydes provides useful synthetic intermediates, but it requires multistep reactions and generates significant amounts of waste. We considered such reactions using nitromethane as a C1 source through nitroolefin formation, partial hydrogenation to oximes, and hydration of oximes; however, the control of selectivity in the second reaction is challenging. To achieve this pathway

  芳基醛的同系化提供了有用的合成中间体，但它需要多步反应并产生大量废物。我们考虑了使用硝基甲烷作为 C1 源通过硝基烯烃形成、部分氢化成肟和肟水合的反应；然而，第二反应中选择性的控制具有挑战性。为了实现这一途径，开发了用于选择性氢化的氮掺杂碳嵌钯纳米颗粒催化剂。我们发现氮掺杂剂的存在有效地调整了催化活性，使其在环境压力下表现出几乎完美的选择性、高活性和可重复使用性。然后，我们在批处理和流动系统中进行了三步同源化反应，只需要一个纯化步骤。
• Synthesis, analysis and rearrangement of novel unnatural glucosinolates

  As part of a structure activity study to examine the interaction of glucosinolates with leaf surfaces,a number of glucosinolates were synthesised bearing novel side chain functionalities. These included 7-carboxyheptyl, heptyl, and naphthyl side chains. For the carboxyheptyl glucosinolate, a novel intramolecular rearrangement reaction was observed during the final deprotection step, which generated an ester attached to the C-3 of glucose. Studies by H-1 NMR spectroscopy showed that the hydrophobic side chain associated with one face of the glucose ring and it was proposed that this was the driving force for the rearrangement. Similar hydrophobic interactions were also observed between the heptyl and naphthyl side chains and the glucose. (C) 2001 Elsevier Science Ltd. All rights reserved.
