2-(1-Adamantyl)-1, 3-butadiene (1) was prepared by p-toluenesulfonic acid-catalyzed dehydration of the corresponding allyl alcohol 5. The Diels-Alder reactions of 1 with a variety of dienophiles proceeded smoothly to give adamantane-substituted six-membered carbo-and heterocycles. Similarly, [4+2] cycloaddition reactions of adamantane-bearing heterodienes afforded some adamantyl-oxazines.
2-(1-
金刚烷基)-
1,3-丁二烯 (1) 是通过
对甲苯磺酸催化的相应
烯丙醇5的脱
水反应制备的。1与多种二烯亲和物进行的Diels-Alder反应顺利进行,生成了
金刚烷取代的六元碳环和
杂环化合物。同样地,带有
金刚烷的杂二烯的[4+2]环加成反应也得到了一些
金刚烷基-嗪类化合物。
