A variety of α-substituted butenolides was efficiently synthesized starting from commercially available tetronic acid and carboxylic acids in four steps. The effectiveness of this approach is illustrated in the short synthesis of one of the first butenolide acetogenins: (+)-ancepsenolide.
从市售的特电子酸和羧酸开始,分四步有效地合成了各种 α-取代的丁烯内酯。这种方法的有效性在第一个丁烯内酯 acetogenins 之一的短合成中得到了说明:(+)-ancepsenolide。
