  • Terpenoid derivatives of 4-hydroxypropiophenone as juvenoids and juvenogens I.
    作者:Jitka Kahovcová、Miroslav Romaňuk
    DOI:10.1135/cccc19811413
    日期:——

    Using the reactions modifying the chemical structure of 4-(3,7-dimethyl-2,6-octadienyloxy)propiophenone and 4-(3,7-dimethyl-2-octenyloxy)propiophenone a number of potential juvenoids and juvenogens were synthetized.

    使用反应修改4-(3,7-二甲基-2,6-辛二烯氧基)丙苯酮和4-(3,7-二甲基-2-辛烯氧基)丙苯酮的化学结构,合成了多种潜在的幼虫激素和幼虫激素。
  • [EN] PROCESS FOR THE OXIDATION OF MESITOL<br/>[FR] PROCÉDÉ D'OXYDATION DU MÉSITOL
    申请人:BASF SE
    公开号:WO2012107877A1
    公开(公告)日:2012-08-16
    The invention relates to a process for the oxidation of mesitol with singlet oxygen, which is re- leased from hydrogen peroxide, this release taking place in the presence of a bismuth com- pound as catalyst. In the process, 2,4,6-trimethylquinol is formed in high yield and selectivity as product, which can be used in further reactions for the synthesis of vitamins and in particular of vitamin A and vitamin E.
    该发明涉及一种使用单线态氧氧化甲苯酚的方法,该单线态氧来自过氧化氢,该释放发生在存在化合物作为催化剂的情况下。在该过程中,以高产率和选择性形成2,4,6-三甲基喹啉作为产物,该产物可以用于进一步反应,用于合成维生素,特别是维生素A和维生素E。
  • <b>Small-Ring Compounds. XXXVI. 3-Methylenecyclobutyl Bromide and 1-Methylcyclobut-2-enyl Bromide</b>
    作者:Edgar F. Kiefer、John D. Roberts
    DOI:10.1021/ja00864a021
    日期:1962.3
    3-Methylenecyclobutyl bromide and 1-methylcyclobut-2-enyl bromide have been synthesized from the cycloaddition products of allene with acrylonitrile and vinyl benzoate. The rate constants for solvolysis of the two bromides in aqueous ethanol have been determined and correlated with the solvolysis rates of a series of analogous bromides. 1-Methylcyclobut-2-enyl bromide appears to exhibit some rate enhancement
    丙二烯丙烯腈苯甲酸乙烯酯的环加成产物合成了3-亚甲基环丁基溴和1-甲基环丁-2-烯基。两种化物在乙醇溶液中的溶剂分解速率常数已经确定,并与一系列类似化物的溶剂分解速率相关联。1-甲基环丁-2-烯基化物似乎表现出一定的速率增强,这是由于电子形式上以3-位为中心的交叉环s型相互作用与过渡态中缺电子的1-位。
