An efficient method for the synthesis of O-substituted mandelic acids containing alkenyl, alkynyl, methoxycarbonyl, or phenacyl fragments via the Lewis acid-catalyzed reaction of 1,3-dioxolan-4-ones with different C-nucleophiles is proposed.
提出了一种有效的方法,该方法通过路易斯酸催化的1,3-二氧戊环-4-酮与不同的C-亲核试剂的反应,合成含有烯基,炔基,甲氧羰基或苯甲酰基片段的O-取代的扁桃酸。
