    摘要: Novel derivatives of 5-thia- and 5-selenopyrimidinone are sound to inhibit the enzyme glycinamide ribonucleotide formyl transferase (GARFT) and amino imidazole carboxamide ribonucleotide formyl transferase (AICARFT). Novel intermediates of these compounds are also disclosed. A novel method of preparing such compounds is also disclosed, as well as methods and compositions for employing the compounds as antiproliferative agents.

    摘要: The invention relates to a process for preparing a substituted 2-amino-benz[cd]indole of the Formula I: ##STR1## The nitro group of a substituted 1-nitro-8-cyano-naphthalene compound is reduced to an amine group to form a substituted 1-amino-8-cyano-naphthalene compound, which is cyclized to form the substituted 2-amino-benz[cd]indole. The reduction and cyclization may be effected in a one-pot procedure using a reducing agent such as stannous chloride, which generates an acid that cyclizes the reduction product. The syntheses of the 1-nitro-8-cyanonaphthalene compound and its precursors are also described.
