The reaction of the stabilized phosphonium ylides 2a, 2b with indolinones 1a, 1b and naphthofuranone 13 afforded the corresponding propylidene and ethylidene derivatives 4a, 4b, 4c, 4d and 14a, 14b. On the other hand, the active phosphacumulenes 5a, 5b react with compounds 4a, 4b, 4c, 4d by [4 + 2]‐cycloaddition to give the stable phosphanylidene indole pyranones 6a, 6b, 6c, 6d, 6e, 6f, 6g, 6h. Although
稳定的磷化氢yl化物2a,2b与吲哚啉酮1a,1b和萘呋喃酮13的反应得到相应的亚丙基和亚乙基衍生物4a,4b,4c,4d和14a,14b。另一方面,活性磷酸ac 5a,5b与化合物4a,4b,4c,4d通过[4 + 2]-环加成反应,得到稳定的亚膦基吲哚吡喃酮6a,6b,6c,6d,6e,6f,6g,6h。尽管化合物14a,14b提供了萘并呋喃吡喃16a,16b,16c,16d和三苯基膦。此外,膦亚基内酯7与化合物4a,4b,4c,4d和14a,14b反应,得到膦亚基环丁烯二氢吲哚9a,9b,9c。分别是1、9d和萘甲酮18a,18b。此外,naphthofuropyridazine 21从腙反应得到19和phosphacumulene 5a中。在体外评估了一些新化合物对结肠和肝细胞癌细胞系的抗肿瘤活性。他们显示的值接近于参考药物阿霉素所记录的值。
