A general and practical catalytic method has been developed for the rapid synthesis of HCTD (heptacyclo[6.6.0.02,6.03,13.04,11.05,9.010,14]tetradecanes) and various new 7,12-disubstituted HCTDs from norbornadienes. Compared to the known approaches, this new protocol avoids stoichiometric metals, utilizes commercially available reagents as catalysts, and affords higher yields and significantly improved
已经开发了一种通用且实用的催化方法,用于快速合成HCTD(七环[6.6.0.0 2,6 .0 3,13 .0 4,11 .0 5,9 .0 10,14 ]十四烷)和各种新的催化方法。来自降冰片二烯的7,12-二取代的HCTD。与已知方法相比,该新规程避免了化学计量的金属,利用了可商购的试剂作为催化剂,并提供了更高的收率和显着提高的选择性。此外,首次发现四环烷经历类似的内,顺,内环加成以高产率得到HCTD。HCTD的衍生化导致有效制备一系列具有生物和材料应用潜力的新型同双功能和异双功能支架。
