  The furan approach to oxacycles: synthesis of medium-size 2,3-disubstituted oxacycles

  摘要：

  We describe an efficient new approach for the synthesis of medium-size oxacycles that is based on the oxidation of a furan ring with singlet oxygen followed by an intramolecular Michael addition. This present study enlarges the scope of the furan approach strategy for the synthesis of oxepanes. (C) 2004 Elsevier Ltd. All rights reserved.

• The Methoxyallene Approach to Oxacycles, Part 2: Stereoselective Synthesis of 2,3-Disubstituted Oxepanes

  DOI：10.1055/s-2004-834946

  日期：——

  2,3-Disubstituted oxepanes 3 and 4 were stereoselectively synthesized from methoxyallene (1) and iodide 2. The trans stereochemistry of diol 3 was established by NMR studies of the bicyclic precursor 10, while the cis stereochemistry of 4 was secured by using the highly diastereoselective reducing agent L-Selectride.

  2,3-二取代的氧杂环丁烷 3 和 4 由甲氧基丙二烯 (1) 和碘化物 2 立体选择性合成。二醇 3 的反式立体化学是通过双环前体 10 的 NMR 研究确定的，而 4 的顺式立体化学是通过使用高度非对映选择性还原剂 L-Selectride。
