It is demonstrated for the first time that carboxylic ortho esters may be reduced to acetals using hydrogen as the reducing agent. Hydrogenolysis was performed under mild conditions over commercially available hydrogenation catalysts (5% Pd/C and 5% Pt/C). The present method is especially useful for the selective transformation of carboxylic acids and lactones into acetals.
首次证明可以使用氢作为还原剂将羧酸原酸酯还原为缩醛。氢解在温和条件下在市售的氢化催化剂(5% Pd/C 和 5% Pt/C)上进行。本方法特别适用于将羧酸和内酯选择性转化为缩醛。
