一般描述
三氟甲磺酸二丁硼（二丁基三氟硼酸盐，Bu2BOTf）是有机金属试剂。能有效地促进苄基和烯丙基有机铜试剂的1,4-加成反应。
应用
三氟甲磺酸二丁硼 (ETMS) 可用于以下研究：
- 赤式羟醛的立体选择性和区域选择性合成
- 作为促进剂，用于溶液和聚合物负载的三氯乙酰亚胺酯糖基化
- 通过一步Mukaiyama醇醛反应合成β-烷氧羰基化合物
- 醇醛环化，用于立体选择性合成环醚
- 作为试剂形成硼烯醇盐
- 作为络合剂，分离1-酰基二吡咯甲烷
- 作为促进剂，促进醛与O-苄基或 O-烯丙基乙醇酸酯的[1,2] -Wittig反应，无需强碱即可高产量地生成两个连续立体中心（1,2-二醇）

[reaction: see text] Dibutylboron triflate/diisopropylethylamine mediated aldol-type cyclization provides an expedient route for the stereoselective synthesis of cyclic ethers in a single step. The method is highly efficient for the stereoselective synthesis of 4-cis-tetrahydropyranones. The reaction is proposed to proceed

A boron-mediated syn- and anti-stereoselective aldol reaction giving rise to various beta-hydroxyenones was coupled to a Pd((II))-mediated oxidative cyclization to give 2,3,6-trisubstituted syn- and anti-dihydropyranones in good yields. The Pd((II))-mediated oxidative cyclization was expanded to alpha-hydroxyenones leading to furan-3(2H)-one derivatives
