A simple and efficient one-pot preparation of α-ketoacetals from substituted acetophenones and triethylorthoformate in the presence of H2SeO3 and BF3·Et2O as catalyst has been developed. The desired products are obtained in good yields by a simple protocol involving neat and mild reaction conditions. The present methodology provides an attractive alternative method for the preparation of α-ketoacetal
开发了一种简单有效的一锅法,在H 2 SeO 3和BF 3 ·Et 2 O作为催化剂的情况下,由取代的苯乙酮和原甲酸三乙酯制备α-酮缩醛。通过涉及纯净的和温和的反应条件的简单方案以高收率获得所需产物。本方法提供了制备α-酮缩醛衍生物的有吸引力的替代方法。
