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。[1]

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[2]
  • 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[1]
  • 通过一步Mukaiyama醇醛反应合成β-烷氧羰基化合物[3]
  • 醇醛环化，用于立体选择性合成环醚[4]
  • 作为试剂形成硼烯醇盐[5]
  • 作为络合剂，分离1-酰基二吡咯甲烷[6]
  • 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）[7]

one-step Mukaiyama aldol type reaction [reaction: see text] A highly efficient one-step Mukaiyama aldol-type reaction has been developed for the synthesis of beta-alkoxy carbonyl compounds starting from ketones and acetals/ketals. The reaction is mediated by a combination of Bu(2)BOTf and

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

1-Acyldipyrromethanes are important precursors in rational syntheses of diverse porphyrinic compounds. 1-Acyldipyrromethanes are difficult to purify, typically streaking upon chromatography and giving amorphous powders upon attempted crystallization. A solution to this problem has been achieved by reacting the 1-acyldipyrromethane with
Stereo-and regio-controlled aldol synthesis.
