Herein, we report an efficient and practical method for synthesizing α,α-dibromo esters, which are the precursors of ynolates, through the dibromination of aldehydes followed by oxidative esterification using iodine. Our method was successfully employed in a large-scale synthesis to yield more than 30 g of dibromo esters. These two steps can be performed in a one-pot manner, which makes the method
在此,我们报告了一种有效且实用的合成α,α-二溴酯的方法,α,α-二溴酯是炔醇化物的前体,通过醛的二溴化,然后使用碘进行氧化酯化。我们的方法已成功用于大规模合成,产量超过 30 克二溴酯。这两个步骤可以以一锅法进行,这使得该方法甚至适用于低沸点的醛。
