  公开（公告）日：2004-12-02

  The invention provides the process illustrated in scheme 1 for synthesizing heterocyclic compounds of formula I. 1 In the process, an isothiocyanate of formula II is initially reacted with a primary amine of formula III to give a thiourea of formula IV. Subsequently, the thiourea of formula IV is converted to the corresponding heterocycle of formula I using a base and a sulfonyl chloride.

  该发明提供了合成式I的杂环化合物的方案1所示的过程。 在该过程中，首先将式II的异硫氰酸酯与式III的初级胺发生反应，得到式IV的硫脲。随后，利用一种碱和磺酰氯将式IV的硫脲转化为相应的式I的杂环化合物。

  Pyridiniums derived from amino alcohols cyclise to ethers or rearrange to aldehydes on heating. Monopyridiniums from diamines can be acylated or converted into ureas or thioureas: these products cyclise on heating in solution to give dihydro-thiazoles, -4H-thiazines, -oxazoles, -4H-oxazines, or tetrahydro-3H-thiazepines.

  衍生自氨基醇的吡啶鎓在加热时会环化为醚或重排为醛。来自二胺的单吡啶鎓可被酰化或转化为脲或硫脲：这些产物在溶液中加热后环化，得到二氢噻唑，-4H-噻嗪，-恶唑，-4H-恶嗪或四氢-3H-噻嗪类。

• A convenient method for the synthesis of 2-amino substituted aza-heterocycles from N,N′-disubstituted thioureas using TsCl/NaOH

  日期：2004.10

  p-Toluenesulfonyl chloride (TsCl)/NaOH has been introduced as reagent combination for the synthesis of 2-amino-oxa- or 2-amino-thiazolidines from N-(2-hydroxyethyl)-thioureas, but its general application in heterocycle synthesis has not been investigated. In this paper the convenient and efficient synthesis of a variety of 2-amino-substituted 1-aza 3-(aza, oxo or thio) heterocycles of different substitution and ring sizes is described. The application of polymer-supported TsCl facilitates work-up and renders the reaction conditions very suitable for parallel or robot synthesis. (C) 2004 Elsevier Ltd. All rights reserved.
