5,6,7-Trimethoxy-2-methylisoquinolin-1(2H)-one Usage And Synthesis
DescriptionThe aerial portions of Thalictrum minus yield this alkaloid which has been shown to possess the structure of 1: 2-dihydro-5: 6: 7-trimethoxy-2-methyl-loxoisoquinoline. It gives an ultraviolet spectrum in EtOH with absorption maxima at 247, 270, 281, 293 and 332 nm. The base is stable to both acid and alkaline hydrolysis and hydrogenation with LiAlH4,NaBH4 or PtO2 up to 100°C but catalytic hydrogenation at 80°C and 80 atmospheres furnishes the dihydro derivative, m.p. 104-6°C.
