condense with a variety of amine, aniline and hydrazine derivatives to form diverse isomeric benzopyrans of types of 9 and 10. The benzopyrans 4–9 which contain a 3,4,5-trimethoxyphenyl ring are active anti-tumor agents, particularly against human breast, CNS and colon cancer cell lines, total growth inhibition of these tumors often occurring in vitro at concentrations as low as 10−5-10−6 moles/1.

1-3型吡咯烷,吗啉和哌啶衍生的曼尼希碱与丙酮,丙醛和丁醛反应形成4-8型2-甲基和3-甲基苯并吡喃。这些苯并吡喃的水解产生醇性苯并吡喃,其容易与多种胺,苯胺和肼衍生物缩合以形成9和10类型的各种异构体苯并吡喃。含有3,4,5-三甲氧基苯基环的苯并吡喃4-9是活性抗肿瘤剂,尤其是对人乳腺癌,中枢神经系统和结肠癌细胞系的抑制作用,这些肿瘤的总生长抑制作用通常在体外以低至10 -5 -10 -6摩尔/ 1。由于它们的体外活性和不寻常的结构,已选择了许多这类苯并吡喃用于体内异种移植物测试,以对抗乳腺癌和其他易感人类癌症。
