  间苯三酚和vic多羰基化合物之间的反应：双极面碗形化合物Kim合成的扩展和机理研究

  摘要：

  金并通过间苯三酚和茚三酮之间的一锅反应意外地合成了新的cavitand。通过用苯并[ n ]茚三酮代替茚三酮可得到更深的空洞。同时使用茚三酮和苯并[ f ]茚三酮进行反应，可提供较低对称性的“混合碗”。其他环状聚酮，例如1，2-茚满二酮和四氧嘧啶与间苯三酚仅形成部分封闭的结构。该反应中中间体化合物的晶体学研究证实了金的假设，即碗的形成涉及半缩环的开环和重排。

  Serendipitous one-pot synthesis of brand-new, bowl-shaped molecular architecture from phloroglucinol and ninhydrin

  摘要：

  We prepared a brand-new, bowl-shaped molecular architecture in one step from the reaction of ninhydrin and phloroglucinol in acetic acid in excellent yield (95%) in a one-pot reaction and the bipolarofacial nature of this compound was confirmed by its X-ray structure.

  A method for appending the ascorbyl moiety onto the framework of phenolic natural products has been developed. This reaction proceeds in two steps from.-ascorbic acid and employs acetic acid catalysis. Excellent stereoselectivity is observed during C C bond formation between the phenolic compound and dehydroascorbic acid, and the process is also chemoselective for phenol derivatives bearing electron-donating substituents in each of the 1, 3, and 5 positions. Further, good regioselectivity was also observed when phenols lacking an axis of C-2 symmetry were employed. This method has led to the synthesis of (-)-ascorbyl phloroglucinol as well as the tetracyclic core of ascorbyl-modified catechin natural products. (C) 2011 Elsevier Ltd. All rights reserved.
