  A simple and environmentally benign synthesis of 2-amino-4H-chromene is described using hydrotalcite as a solid base catalyst in aqueous medium. The catalysts were prepared by a co-precipitation method and well characterized by various techniques such as XRD, FT-IR, SEM and the basicity was found using the phenol adsorption method. The reusability of the catalyst, use of water as a green solvent and easy isolation of the product along with good yields make the present protocol sustainable and advantageous compared to conventional methods.

  A series of polyalkoxy substituted 7-hydroxy- and 7-methoxy-4-aryl-4H-chromenes were evaluated using the sea urchin embryo model to yield several compounds exhibiting potent antimitotic microtubule destabilizing activity. Data obtained by the assay were further confirmed in the NCI60 human cancer cell screen. The replacement of methylenedioxy ring A and lactone ring D in podophyllotoxin analogues by 7-methoxy, 2-NH2, and 3-CN groups in 4-aryl-4H-chromenes resulted in potent antimitotic microtubule destabilizing agents. Feasible synthesis and high yields render 7-methoxy-4H-chromenes to be a promising series for further anticancer drug development.
