The type two intramolecular Diels-Alder reaction, when coupled with bridged to fused ring interchange, provides an efficient stereoselective route to fused 5,7- and 5,8-ring systems. This methodology has been utilized in the total synthesis of (±)-ledol, an aromadendrane sesquiterpene.
当与桥接至稠合环互换连接时,第二种分子内Diels-Alder反应可为稠合的5,7-和5,8-环系统提供有效的立体选择性途径。该方法已用于全合成(±)-ledol(一种芳香型龙脑倍半萜烯)。
