  New [11C]Phosgene Based Synthesis of [11C]Pyrimidines for Positron Emission Tomography

  摘要：

  Thymine, 5-FU, and uracil were successfully synthesized through a procedure involving a cyclocondensation of triphosgene with newly developed alpha-substituted beta-aminoacrylamides intermediates (1a, X = Me; 1b, X = F; 1c, X = H). The radioligands [2-C-11]thymine and [2-C-11]5-fluorouracil were synthesized in high radiochemical yields in 16-17 minutes from the end of bombardment by applying the cyclocondensation method with [C-11]COCl2,

  Two novel series of 2-pyridones were synthesized by transposition of the nitrogen of 4-quinolones to the bridgehead position. This subtle interchange of the nitrogen atom with a carbon atom yielded two novel heterocyclic nuclei, pyrido[1,2-alpha]pyrimidine and quinolizine, which had not previously been evaluated as antibacterial agents and were found to be potent inhibitors of DNA gyrase. Quinolizines

  通过将4-喹诺酮类的氮转位至桥头位置，合成了两个新颖的2-吡啶酮系列。氮原子与碳原子的这种微妙的交换产生了两个新的杂环核，吡啶并[1,2-α]嘧啶和喹啉嗪，它们先前未被评估为抗菌剂，并且被发现是DNA促旋酶的有效抑制剂。（S）-45a（ABT-719）等在9位甲基的喹唑啉酮具有出色的广谱抗菌活性。最值得注意的是，它们对耐药菌具有活性，例如耐甲氧西林的金黄色葡萄球菌，耐万古霉素的肠球菌菌株和耐环丙沙星的生物。此外，2-吡啶酮还具有良好的理化和药代动力学特性。这些2-吡啶酮是通过10-17个线性转化从商购可得的起始原料合成的。通过X射线晶体学分析确定由该序列产生的加合物（S）-45a（ABT-719）的结构。
