The total synthesis of Hirtellanine A was accomplished by two different synthetic approaches. Hirtellanine A was assembled using a one-pot, tandem acid-mediated deprotection and tautomerization cascade starting from quinone derivative 23. The key features

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.
