This invention encompasses compounds of formula (I)
wherein:
n is
0, 1 or 2, A is X or
Ra is
hydrogen or nitro; and
R1, R2, X, Y and W are variables. These compounds are useful as intermediates for production of certain cycloalkyl and azacycloalkyl pyrrolopyrimidines which are highly selective agonists, antagonists or inverse agonists for GABAa brain receptors or prodrugs thereof and are useful in the diagnosis and treatment of anxiety, sleep, and seizure disorders, overdose with benzodiazepine type drugs, and enhancement of alertness.
本发明包括式 (I) 的化合物
其中
n 是
0、1 或 2,A 是 X 或
Ra 是
氢或硝基;以及
R1、R2、X、Y 和 W 为变量。这些化合物可作为生产某些环烷基和氮杂环烷基吡咯并嘧啶的中间体,它们是 GABAa 脑受体或其原药的高选择性激动剂、拮抗剂或反向激动剂,可用于诊断和治疗焦虑、睡眠和癫痫发作障碍、苯二氮卓类药物过量以及提高警觉性。
