The efficient 'on water' β‐borylation using bis(pinacolato)diboron agent was achieved with a newly developed catalytic system based on basic copper carbonate and various ligands. The catalytic system was used for β‐borylation of various Michael acceptors, alkenes and alkynes. The presented methodology was successfully applied to the novel synthesis of β‐alcohol type sitagliptin side chain precursor
使用基于碱性碳酸铜和各种配体的新开发的催化系统,使用双(频哪醇)二硼剂实现了高效的“水上”β-硼化。催化体系用于各种迈克尔受体,烯烃和炔烃的β-硼化反应。所提出的方法已成功地通过水基高度对映选择性的β-硼化和随后的氧化过程成功地用于β-醇型西他列汀侧链前体的新型合成。版权所有©2013 John Wiley&Sons,Ltd.
