  甲磺酸介导的环化和 γ-氨基炔酮的 Meyer-Schuster 重排：获得对映纯吡咯烷环外乙烯基酰胺

  摘要：

  α-和β-氨基炔酮已被广泛用于在各种亲电子试剂如质子酸或金（I）存在下制备杂环。在本文中，我们公开了前所未有的吡咯烷外环乙烯基酰胺的形成，以代替预期的氮杂酮或哌啶酮，从氨基酸衍生的 γ-氨基炔酮开始。该过程包括将受保护的氮串联 1,2-加成到羰基，然后进行 Meyer-Schuster 重排，从而有效地提供对映体纯的吡咯烷外环乙烯基酰胺。该序列被金盐催化的效果很差，但在甲磺酸的存在下被证明是非常有效的。

  日期：2008.3.1

  scalable synthetic route profits from the strategic utilization of substrate-controlled manipulations for the iterative installation of the requisite stereogenic centers. The key transformations include a diastereoselective modified Claisen condensation, a chemo- and diastereoselective reduction of a β-keto ester, and the substrate-directed hydrogenation of a dehydroamino ester derivative. During the course

  Starting from D-glutamic acid (5), the bicyclic compounds 4a and 4b were synthesized via17 (Schemes 1 and 2). The reaction leading to 4g and 4h with LiCuPh2 was not successful. But treatment of the N-protected model lactams 19, 21, and 22 with Li2Cu(CN)Ph2 gave the amino ketones 24, 26, and 27, respectively (Scheme 3). The desired compound 23 was obtained from 20.
