  The present invention provides a process for making 2-amino-2-imidazoline, guanidine, and 2-amino-3,4,5,6-tetrahydroyrimidine derivatives by preparing the corresponding activated 2-thio-subsituted-2-derivative in a two-step, one-pot procedure and by further reacting yields this isolated derivative with the appropriate amine or its salts in the presence of a proton source. The present process allows for the preparation of 2-amino-2-imidazolines, quanidines, and 2-amino-3,4,5,6-tetrahydropyrimidines under reaction conditions that eliminate the need for lengthy, costly, or multiple low yielding steps, and highly toxic reactants. This process allows for improved yields and product purity and provides additional synthetic flexibility.

  本发明提供了一种制备2-氨基-2-咪唑啉、胍和2-氨基-3,4,5,6-四氢嘧啶衍生物的方法，通过在两步一锅程序中制备相应活化的2-硫代取代-2-衍生物，并进一步在质子源存在下将得到的孤立衍生物与适当的胺或其盐反应。本方法允许在消除了冗长、昂贵或多次低产率步骤以及高毒性反应物的反应条件下制备2-氨基-2-咪唑啉、胍和2-氨基-3,4,5,6-四氢嘧啶。该方法提高了产率和产品纯度，并提供了额外的合成灵活性。
• Potent Antimalarial Activity of 2-Aminopyridinium Salts, Amidines, and Guanidines

  We describe the design, synthesis, and antimalarial activity of 60 bis-tertiary amine, bis-2(1H)-imino-heterocycle, bis-amidine, and bis-guanidine series. Bis-tertiary amines with a linker from 12 to 16 methylene groups were active against the in vitro growth of Plasmodium falciparum within the 10(-6)-10(-7) M concentration range. IC50 decreased by 2 orders of magnitude for bis-2-aminopyridinium salts, bis-amidines, and bis-guanidines (27 compounds with IC50 < 10 nM). Increasing the alkyl chain length from 6 to 12 methylene groups led to increased activity, while beyond this antimalarial activity decreased. Antimalarial activities appear to be strictly related to the basicity of the cationic head with an optimal pK(a) over 12.5. Maximal activity occurs for bis-2-aminopyridinium, two C-duplicated bis-amidines, and three bis-guanidines, with IC50 values lower than 1 nM. In. comparison to similar quaternary ammonium salts, amidinium compounds have distinct structural requirements for antimalarial activity and likely additional binding opportunities on account of their hydrogen-bond-forming properties.

  ABSTRACT Cyclic guanidine hydroiodides were obtained in one step by the reactions of isothiouronium iodides with an equimolar amount of various amines in tetrahydrofuran. The obtained hydroiodides were neutralized with sodium hydroxide or anionic exchange resin to afford the corresponding substituted cyclic guanidines in quantitative yields. GRAPHICAL ABSTRACT
