• In situ intramolecular catalytic 1,2-addition of allenoates to cyclic ketones towards polycyclic allenoates
  作者：Clément F. Heinrich、Michel Miesch、Laurence Miesch

  DOI：10.1039/c4ob02451f

  日期：——

  Sequential deprotonation, isomerization of 3-alkynoates and subsequent 1,2-addition led to bicyclic allenoate in the presence of a catalytic amount of Cs2CO3. Cyclization proceeds in a totally stereoselective manner in the case of the two-carbon linker chain. A one-pot reaction starting from alkynyl ketones afforded tricyclic fused ring systems with good yields.

  在催化量的Cs 2 CO 3存在下，连续的去质子化，3-链烷酸酯的异构化以及随后的1,2-加成导致双环烯丙酸酯。在二碳连接子链的情况下，环化以完全立体选择性的方式进行。从炔基酮开始的一锅反应得到具有良好收率的三环稠合环系统。

  Herein we describe the first transition-metal-free ring expansion of four-membered rings to 1-tetralones from 3-substituted heteroaromatic compounds, and the first example of an oxetanol ring expansion to an oxa-tetralone. We also experimentally investigate the mechanism of the silver-mediated ring expansion and elucidate the active oxidant in these systems using electrochemical techniques.

  在本文中，我们描述了四元环从3-取代的杂芳族化合物到1-四氢萘酮的第一个无过渡金属的环扩环，以及氧杂环丁醇环扩到氧-四氢萘酮的第一个例子。我们还实验研究了银介导的扩环机理，并使用电化学技术阐明了这些系统中的活性氧化剂。

  A facile and transition-metal-free ring expansion of the cyclobutanol moiety to 4-tetralones fused to heteroaromatic systems is described. The oxidative ring expansion proceeds rapidly and regioselectively through mediation by N-bromosuccinimide and acetonitrile in satisfactory to good yields. The preparation of precursors and the ring expansion have proven to be scalable and are straightforward to
