  Intramolecular Cyclization of β-Alkynylpropanamides to γ-Alkylidene-γ-butyrolactams

  摘要：

  A general method for the base-catalized intramolecular cyclization of beta-alkynylpropanamides 1 to gamma-alkylidene-gamma-butyrolactames 2 (and 3) was established. Reactions of beta-alkynylamides 1c-h, possessing alkyl groups at the terminal acetylenes, in the presence of a catalytic amount of LiN(TMS)(2)/AgOTf (= 2:1) in toluene gave exclusively (Z)-alkylidenelactames 2c-h in good yields.

  efficient seven-step, protecting-group-free first total synthesis of chatenaytrienin-2 based on ring-closing metathesis and C(sp)–C(sp3) Sonogashira coupling with a 36.5% overall yield has been described. The ready availability of starting materials and key Wittig olefination, ring-closing metathesis, Lindlar reduction, and C(sp)–C(sp3) coupling makes this strategy applicable for the synthesis of various unbranched

  was synthesized from naturally occurring cyclitol, L-quebrachitol via the conduramine derivative, which was prepared regio- and stereoselectively by the Pd-catalyzed azidation of the allyl carbonate derivative. Condensation of phytosphingosines with 2-acetoxy fatty acid residue, followed by glycosidation, furnished the total synthesis. This work established an effective synthetic pathway to a wide

  作者：Juliane Adrian、Christian B. W. Stark

  DOI：10.1021/ol502849y

  日期：2014.11.21

  The first total synthesis of muricadienin, the unsaturated putative precursor in the biosynthesis of trans- and cis-solamin is described. Key steps in the synthesis are a chemoselective hydroboration, a Z-selective Wittig reaction, and a Fries rearrangement for introducing the terminal α-substituted butenolide. Thus, muricadienin can be synthesized in 11 steps from commercially available starting materials

  作者：Yuji Koseki、Shuichi Kusano、Daisuke Ichi、Keiji Yoshida、Tatsuo Nagasaka

  日期：2000.11

  A general method was devised for the LiN(TMS)(2)/AgOTf (=2:1)-catalyzed intramolecular (5-exo-dig) cyclization of beta -alkynylamides 1 possessing alkyl, aryl or no functional groups at the terminal alkynes, to 5-alkylidene-2-pyrrolidinones 2. These 5-alkylidene-2-pyrrolidinones were oxidized to the diol-type alkoxylactams 3 by dimethyldioxirane (DMD) or mCPBA in MeOH. These alkoxylactams are useful as tertiary N-acyliminium ion precursors for the synthesis of threo-5-(1-hydroxyalkyl)-2-pyrrolidinone derivatives 5. (C) 2000 Elsevier Science Ltd. All rights reserved.
