4-[[(1R)-1,2,3,4-Tetrahydro-7,8-dimethoxy-2-methylisoquinolin-1-yl]methyl]phenol

The New Caledonian plant Cryptocaria longifolia Kostermans yields this alkaloid which has been obtained as a pale yellow amorphous powder with no definite melting point. The base is laevorotatory with a specific rotation of raMO -72° (c 0.2, EtOH) and gives an ultraviolet spectrum in EtOH with absorption maxima at 255 and 279-281 nm.
