  A one-pot three-component approach for the synthesis of thiazol-2-imines has been described by the reaction of amine, phenyl isothiocyanate and β-nitroacrylate in [Hbim]BF4 ionic liquid. The method is applicable for aromatic, benzylic, aliphatic and cyclic amines. Reusable reaction media, regioselectivity, mild reaction condition, catalyst free and high yield of products are the salient features of

  通过胺，异硫氰酸苯基酯和β-硝基丙烯酸酯在[Hbim] BF 4离子液体中的反应，已经描述了一种用于合成噻唑-2-亚胺的单锅三组分方法。该方法适用于芳族，苄基，脂肪族和环状胺。可重复使用的反应介质，区域选择性，温和的反应条件，无催化剂和高收率的产品是该方案的主要特征。

• Study of reactions between 1,2-diaza-1,3-butadienes and N,N′-diaryl- or N,N′-dialkylthioureas

  1,2-Diaza-1,3-butadienes react with N,N'-diarylthioureas to give 2-(arylimino)-2,3-dihydrothiazole derivatives, whereas with N,N'-dialkylthioureas to afford 5,5-disubstituted 3-alkyl-2-(alkylimino)-thiazdidin-4-one derivatives. Under basic conditions, these last products surprisingly give rise to 2-thioxo-1,3,7-triazaspiro[4.4]non-8-en-4-one and 5-oxo-4-(4-substituted 5-oxo-2-thioxoimidazolidin-4yl)-2,5-dihydro-1H-pyrazole derivatives. In acidic medium, 5,5-disubstituted 3-alkyl-2-(alkylimino)-thiazolidin-4-ones are converted into 2-(alkylimino)-1-thia-3,7-diazaspiro[4.4]non-7-en-4-ones. X-Ray crystal structures of two products were determined. (C) 1999 Elsevier Science Ltd. All rights reserved.
