A unique differential reactivity between dihydroisoquinolines and 3-nitrocoumarins was observed and was exploited for the efficient construction of lamellarins and their isomeric benzofuran-8-oxoprotoberberine derivatives under acid-catalyzed or base-promoted conditions. Further, these prepared aryl-substituted benzofuran-8-oxoprotoberberine derivatives bearing electron-donating substituents on benzofuran moiety are found to be benchtop stable but light-sensitive, and can undergo oxidative ring-opening reaction to give the corresponding keto products when exposed to visible light under aerobic conditions.

experimental part, p. 638 - 645 (2010/03/30)
The total synthesis of the natural compound (8S*, 14S*)-8-(4'hydroxybenzyl)-2,3-dimethoxyberbin-10-ol and its C-8 epimer has been conveniently developed by making use of the diastereoselective Stevens rearrangement of the corresponding N-(arylmethyl)berbi
