    名称:
    α,α'-二溴代酮与伯胺反应生成的α-亚氨基酮和α-二亚胺与Favorskii重排产物
    摘要:
    脂族无环α,α′-二溴酮与伯胺的反应产生α-亚氨基酮和α-二亚胺。两种反应产物都可以在适当的反应条件下选择性地获得。受位阻的α,α-二溴酮不与伯胺反应,尽管在强迫条件下可以诱导Favorskii重排。在甲醇水溶液中,α,α'-二溴代酮与伯胺反应生成Favorskii重排,而不是α-亚氨基酮的形成。脂环族α,α'-二溴代酮对伯胺的行为不同,因为五元环提供2-(N-烷基)氨基-2-环戊烯酮,而六元环引起Favosskii环收缩。

  • Action des homocuprates sur les cetones α,α′-dibromees. Une nouvelle methode de synthese de cetones encombrees
    作者:C. Lion、J.-E. Dubois
    DOI:10.1016/0040-4020(75)85061-7
    日期:1975.1
    The reaction between alkyllithium homocuprates and α,α′-dibromoketones permits the monoalkylation of ketones after hydrolysis of the reaction intermediate; the latter reacts with an excess of alkyl halide and gives the dialkylated product. Four alkylation reactions (methylation, ethylation, isopropylation and t-butylation) of α,α′-dibromoketones have been studied. While monoalkylation leads to secondary/primary
    烷基锂均铜酸盐与α,α'-二溴代酮之间的反应使反应中间体水解后酮单烷基化。后者与过量的烷基卤反应,得到二烷基化产物。研究了α,α′-二溴酮的四个烷基化反应(甲基化,乙基化,异丙基化和叔丁基化)。虽然单烷基化从双伯和双仲结构产生仲/伯和叔/仲酮,但是二烷基化允许合成双仲和双叔酮。但是,不可能以相同的结构引入两个第三级。

  • Metal-Mediated [6 + 3] Cycloaddition Reactions of Fulvenes. A Novel Approach to Indan Systems
    作者:Bor-cherng Hong、Si-shoung Sun、Yann-chien Tsai
    DOI:10.1021/jo970984j
    日期:1997.10.1
    The [6 + 3] cycloaddition of 2-oxyallyl cations to the electron rich fulvene ketene acetal provides an efficient route to the indan skeleton. The structures of these indan adducts were assigned by extensive 2D NMR experiments. Direct hydrolysis of these ketal adducts affords the corresponding diketones or indens. Reaction of the fulvene ketene thioacetal as well as the tandem [6 + 3]-[4 + 3] cycloadditions were also studied. A mechanism is proposed which may account for the origin of stereo-and regioselectivity in this cycloaddition.
