Abstract An efficient one-pot procedure has been developed for the synthesis of previously unknown 1,1′-(9-selenabicyclo[3.3.1]nonane-2,6-diyl)dipyridinium dibromides containing acetal moieties via transannular addition of selenium dibromide to Z,Z-cycloocta-1,5-diene, followed by reaction with pyridine-3- and 4-carbaldehyde acetals. The yields of the target products range from 80 to 97%.
摘要 已经开发了一种有效的一锅法,用于通过将二溴化硒跨环加成到Z , Z -cycloocta-1,5-diene,然后与吡啶-3-和 4-甲醛缩醛反应。目标产品的收率范围为 80% 至 97%。
