    名称:
    (−)-Astrogorgiadiol: a shorter route to A-ring synthon
    摘要:
    A new route to the key A-ring/C-ring precursor synthon of (-)-astrogorgiadiol is described, for the strategy based on Robinson annulation. This synthon is also key for the synthesis of other related calicoferols and astrogorgols. The route takes full advantage of the opening of 6-methoxy-1-tetralol with bis(sym-collidine) bromine(I) triflate. It involves a new protection-deprotection sequence of an enone. It is the shortest synthesis to date, consisting of seven steps. (C) 2013 Elsevier Ltd. All rights reserved.

  • Formation of Spirocyclic Compounds from Heck Cyclizations Invoking Cyclic Enamides
    作者:Gedu Satyanarayana、Martin E. Maier
    DOI:10.1021/jo800650e
    日期:2008.7.1
    (2-bromophenyl)ethyl substituent in the 5-position produces spirocyclic products, imides 14 and amides 15. The formation of these products can be explained by insertion of the enamide double bond into the initial aryl−Pd bond followed by oxidation or reduction of the organopalladium intermediate. Alternatively, formation of these spiro compounds might proceed via acyliminium ion intermediates.
    钯介导的3,4-二氢-2(1 H)-吡啶酮12在5位具有(2-溴苯基)乙基取代基的转化产生螺环产物,酰亚胺14和酰胺15。这些产物的形成可以通过将烯酰胺双键插入到初始的芳基-Pd键中,然后将有机钯中间体氧化或还原来解释。备选地,这些螺环化合物的形成可以通过酰基酰亚胺离子中间体进行。
  • Bis(sym-collidine)bromine(I) hexafluorophosphate as oxidant
    作者:Gérard Rousseau、Sylvie Robin
    DOI:10.1016/s0040-4039(00)01598-7
    日期:2000.11
    Primary and secondary alcohols in solution in methylene chloride are oxidised with bis(sym-collidine)bromine(I) hexafluorophosphate in good yields to the carbonyl compounds. For secondary and tertiary alcohols in which one of the substituents is a 4-methoxyphenyl group the oxidation takes place by cleavage of the phenyl-sp3 carbon bond and formation of bromoanisole and carbonyl compounds.
