3-Nitrophthalic acid 1 was converted selectively to the two regioisomeric monoesters 2 and 3, which were subsequently transformed via Curtius rearrangement to the corresponding 5- and 8-nitroquinazoline-2,4-diones 4 and 5, respectively. The reduction of the nitro group produced 5- and 8-aminoquinazoline-2,4-diones 6 and 7, respectively, in good yields. The condensation of compounds 7b and 7c with carbon disulfide
将3-硝基邻苯二甲酸1选择性地转化为两个区域异构的单酯2和3,随后通过Curtius重排将其分别转化为相应的5-和5-硝基喹唑啉-2,4-二酮4和5。硝基的还原分别以良好的产率产生了5-和8-氨基喹唑啉-2,4-二酮6和7。化合物7b和7c与二硫化碳在吡啶中的缩合得到三环衍生物9,它们是HIV-1逆转录酶抑制剂4,5,6,7-tetrahydro-5-methylimidazo [4,5,1- jk ] [1,4] benzodiazepin-2(1 H)-one(TIBO)的类似物)。
