P. Rocca et al., CARBOLINES .7. ANISIDINES, CONVENIENT TOOLS TO SYNTHESIZE HYDROXY-BETA-CARBOLINES, Journal of heterocyclic chemistry, 32(4), 1995, pp. 1171-1175
The paper describes a convenient synthesis of hydroxy-beta-carbolines
from commercial anisidines based on key steps such as metalation, cros
s-coupling and cyclization. The first total synthesis of a major cytot
oxic constituent of a marine bryozoan is also reported, the 8-hydroxy-
1-vinyl-beta-carboline.
