Novel spiro heterocycles (5–12) were obtained by the cyclocondensation of 2,6-diaryl-4,4-dimethoxycarbonyl-/4-cyano-4-ethoxycarbonyl-1,4-dihydropyridines(3/4) with hydrazine hydrate, hydroxylamine hydrochloride, urea, and thiourea. All the compounds were characterized by IR, 1H NMR, and 13C NMR spectral data.© 2003 Wiley Periodicals, Inc. Heteroatom Chem 14:513–517, 2003; Published online in Wiley
通过 2,6-二芳基-4,4-二甲氧基羰基-/4-氰基-4-乙氧基羰基-1,4-二氢吡啶(3/4)与水合肼、羟胺的环缩合反应获得新型螺杂环(5-12)盐酸盐、尿素和硫脲。所有化合物均通过 IR、1H NMR 和 13C NMR 光谱数据进行表征。© 2003 Wiley Periodicals, Inc. Heteroatom Chem 14:513–517, 2003; 在线发表于 Wiley InterScience (www.interscience.wiley.com)。DOI 10.1002/hc.10183
