Tandem Diboration–Protoboration of Terminal Alkynes: A Practical Route to α-Substituted Alkenyl Boronates

Abstract

A practical method is introduced for the catalytic conversion of terminal alkynes into α-substituted vinyl boronic esters. The process employs catalytic amounts of nanoparticle-supported gold catalysts and catalytic amounts of copper to effect the overall transformation.

Key words

boron - cross-coupling - AuNPs - alkynes - protonation

The mixture was dissolved in toluene (1.00 mL). The reaction mixture was sealed with a PTFE-lined closed cap, brought out of the dry box and stirred at 80 °C for 24 h. At the completion of the reaction, the crude mixture was passed through a short pad of Celite using diethyl ether as solvent. The filtrate was concentrated and purified by column chromatography (silica gel, 0–1% ethyl acetate/hexane, stained with KMnO₄) to give the desired product as a white solid (296 mg, 82%). ¹H NMR (500 MHz, CDCl₃): δ = 7.24 (m, 2 H), 7.18–7.13 (m, 3 H), 5.79 (s, 1 H), 3.55 (d, J = 1.9 Hz, 2 H), 1.26 (s, 12 H), 1.19 (s, 12 H). ¹³C NMR (126 MHz, CDCl₃): δ = 139.4, 129.8, 128.3, 126.1, 83.8, 83.5, 45.7, 25.0, 24.9.
