A synthesis of novel 4-(substituted)benzyl-5-methylene-2(5H)-furanones involving Stobbe condensation of substituted aldehydes with ethyl levulinate followed by treatment with acetic anhydride in the presence of sodium acetate, has been developed.
已经开发了一种新的4-(取代的)苄基-5-亚甲基-2(5H)-
呋喃酮的合成方法,该方法包括将取代的醛与
乙酰丙酸乙酯进行Stobbe缩合,然后在
乙酸钠的存在下用
乙酸酐处理。
