Synthetic scheme for the preparation of a number of different derivatives of anticancer natural product Psoralidin is described. A convergent synthetic approach is followed using simple starting materials like substituted phenyl acetic esters and benzoic acids. The developed synthetic route leads us to complete the first synthesis of an analogous natural product Lespeflorin I1, a mild melanin synthesis inhibitor. Preliminary bioactivity studies of the synthesized compounds are carried out against two commonly used prostate cancer cell lines. Results show that the bioactivity of the compounds can be manipulated by the simple modification of the functional groups.

2,3,7,8,10-Pentaoxygenated benzophenanthridine alkaloids, sanguilutine (1) and dihydrosanguilutine (2), were efficiently synthesized from the corresponding 2,3,9,10,12-pentamethoxyprotoberberine (8) through a regioselective C(6)-N bond cleavage, followed by recombination between the original C(6) and C(13) positions of compound (8) according to a biomimetic route.
