Alkynes are readily available and multifunctional synthetic intermediates, but their 1,1-oxofunctionalization remains challenging. Herein, we report a 1,1-oxycarbonation of terminal alkynes to construct ketones through sequential borylation, 1,2-carbon migration, and oxidation with Oxone as the proton source and oxidant. The synthetic potential of this transformation is showcased by the broad functional
炔烃是容易获得的多功能合成中间体,但其 1,1-氧代官能化仍然具有挑战性。在此,我们报道了末端炔烃的 1,1-氧碳酸化,通过顺序硼化、1,2-碳迁移和 Oxone 作为质子源和氧化剂的氧化来构建酮。广泛的官能团、放大合成和多样化的产品转化展示了这种转化的合成潜力。
