    • The present invention provides a synthetic route for tetraazacycloalkane preparation which facilitates heteropoly-N-alkylation of the macrocyclic product, and is thereby beneficial for the production of chelating agents and chelates useful in diagnostic imaging. The process involves (i) reacting a tetraazaalkane with a bridging agent to couple four amine nitrogens of said tetraazaalkane to a bridging moiety to yield a fused tricyclic intermediate, (ii) reacting said intermediate to introduce an alkylene bridge between the secondary amine nitrogens in the outer rings of the fused tricyclic intermediate, optionally by decoupling an alkanediylidene bridging moiety from the tertiary amine nitrogens at the ring fusion sites of the fused tricyclic intermediate, and (iii) where necessary, decoupling said bridging moiety to yield a macrocyclic tetraazacycloalkane.
    • 本发明提供了促进大环杂多杂-N-烷基化的四氮杂环烷烃制备的合成路线,从而有利于生产可用于诊断成像的螯合剂和螯合物。 该方法包括(i)使四氮杂链烷烃与桥连剂反应以将四氮杂烷烃的四个胺氮偶联到桥连部分以产生稠合的三环中间体,(ii)使所述中间体在所述仲胺氮中引入亚烷基桥, 稠合三环中间体的外环,任选地通过在稠合三环中间体的环融合位点处将烷二亚烷基桥连部分与叔胺氮脱去,和(iii)必要时将所述桥连部分解偶联以产生大环四氮杂环烷烃。

    • Compounds of the formula: ##STR1## wherein X represents a halogen atom;R.sup.1 and R.sup.2, which may be same or different, each represents a hydrogen atom, or a C.sub.1-4 alkyl group;Het represents a C-attached 3-9 membered, saturated, unsaturated or aromatic heterocyclic ring containing one or more hetero atoms selected from O, N and S and optionally carrying a fused ring and/or optionally substituted by one or more substituents selected from halogen atoms and hydroxy, C.sub.1-4 alkoxy, amino, acylamino, nitro, oxo, C.sub.1-4 alkyl groups and monocyclic carbocyclic and heterocyclic aryl groups having 5 to 8 ring members; such a heterocyclic ring being saturated and having only a single heteroatom when there are 3 or 4 ring members; andalk represents a C.sub.1-4 saturated or unsaturated, straight or branched chain, divalent aliphatic hydrocarbyl group optionally substituted by one or more groups selected from carbocyclic aryl groups and heterocyclic groups as defined for Het above, and the salts thereof have been found to possess metaphase arresting ability which by virtue of its reversibility is of use in combating abnormal cell proliferation. Thus a knowledge of the cell division cycles of the normal and abnormal cells enables a cytotoxic drug to be administered while the abnormal cells are in a phase susceptible to attack and while the normal cells are in a non-susceptible phase.The compounds of the invention are prepared by alkylation, ring closure of the pyrimidine ring, halogenation or ring closure of the heterocyclic ring Het.
