Acetals and ketals are readily deprotected under neutral conditions in the presence of acetone and catalytic amounts of indium(III) trifluoromethanesulfonate (<0.8 mol %) at room temperature or mild microwave heating conditions to give the corresponding aldehydes and ketones in good to excellent yields.
在丙酮和催化量的三氟甲烷磺酸铟(III)(<0.8 mol%)的存在下,在室温或温和的微波加热条件下,在中性条件下,缩醛和缩酮易于脱保护,从而以良好或优异的收率得到相应的醛和酮。
