1,4-Dihydroxy-2-naphthoic acid was used as a substrate for a straightforward five-step synthesis of 3-substituted 1H-benzo[g]isochromene-5,10-diones, with a Michael addition of N-acylmethylpyridinium ylides across 2-hydroxymethyl-1,4-naphthoquinone and a subsequent acid-mediated dehydratation of intermediate hemiacetals as the key steps. The obtained benzo[g]isochromene-5,10-diones were subsequently
1,4-二羟基-2-萘甲酸用作3-取代的1 H-苯并[ g ]异戊二烯-5,10-二酮的简单五步合成反应的底物,同时还添加了N-酰基甲基吡啶鎓基的迈克尔关键步骤是在2-羟甲基-1,4-萘醌中进行分离,随后酸介导的中间半缩醛的脱水。随后将获得的苯并[ g ]异戊烯-5,10-二酮用于进一步的合成加工,以生产新的3,4-二氢苯并[ g ]异戊烯-5,10-二酮和(3,4-二氢-)4a,10a -环氧苯并[ g ]异戊烯-5,10-二酮。筛选所有化合物的细胞毒性和抗微生物作用,发现有趣的细胞毒活性为1对不同癌细胞系的H-苯并[ g ]异戊二烯-5,10-二酮。
