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。
