The ester functionality in β-keto esters is selectively reduced in one-pot, first by enolization using LiHMDS and then reduced with lithium aluminium hydride. This method produces β-hydroxyl ketones from the corresponding β-keto esters in high yield.
首先通过使用LiHMDS烯醇化,然后用氢化锂铝将β-酮酯中的酯官能团一锅选择性地还原。该方法从相应的β-酮酯高产率地产生β-羟基酮。
