In this paper we describe regioselective one-pot preparations of inner-outer-ring 1,3-bis[trimethylsilyloxy]dienes and their Diels-Alder reactions with electron-deficient dienophiles. The dienes were prepared in quantitative yield, and the Diels-Alder reactions proceeded smoothly, regioselectively and with good yields, allowing efficient construction of highly functionalized polycyclic skeletons such
在本文中,我们描述了内外环1,,3-双[三甲基甲
硅烷氧基]二烯的区域选择性一锅法制备及其与缺电子的亲二烯体的Diels-Alder反应。二烯以定量收率制备,并且Diels-Alder反应平稳,区域选择性且收率良好,从而可以高效构建天然和非
天然产物中存在的高度官能化的多环骨架,如
萘呋喃,
苯并呋喃和各种碳环化合物。
