Description
This phenolic alkaloid occurs in Corydalis ochotensis and C. sibirica Pers. It is dextrorotatory with [Q:l~4 + 51.7° (CHCI3) and [o:J~3 + 63.9° (0.1 N/HCI). The methiodide yields tetragonal crystals from MeOH with m.p. 215°C. The 0- methyl ether is ochotensimine (q.v.). The above structure has been confirmed by the total synthesis of the optically inactive form of the alkaloid.
Definition
ChEBI: Ochotensine is a member of isoquinolines.
