generated and added to cyclobutanones to yield mono- to trimethylated [1,1′-bicyclobutyl]-1-ols. Mono- to trimethylated spiro[3.4]octan-5-ols have been prepared from the parent ketone via alkylation and/or addition reactions. Upon treatment with acid, all [1,1′-bicyclobutyl]-1-ols and spiro[3.4]octan-5-ols rearrange to yield a single bicyclo[3.3.0]octene.
已经产生了几种基于取代的
环丁烷的新
格氏试剂,并将其添加到
环丁酮中以产生单甲基至三甲基化的[1,1'-双
环丁基] -1-醇。由母体酮通过烷基化和/或加成反应制备了单-至三甲基化的螺[3.4] octan-5-醇。用酸处理后,所有的[1,1'-双
环丁基] -1-醇和螺[3.4] octan-5-醇重新排列,生成单个双环[3.3.0]
辛烯。
