What is (S)-7-METHOXY-1-METHYL-1,2,3,4-TETRAHYDRO-ISOQUINOLIN-6-OL?

Description

A further isoquinoline alkaloid which occurs in Salsola Richteri, the base is obtained in the form of a microcrystalline powder which is readily soluble in CHC13 or EtOH but only sparingly so in C6H6 or H20. The alkaloid is soluble in aqueous alkalies but insoluble in petroleum ether. The hydrochloride crystallizes as the sesquihydrate in colourless needles, m.p. 14l-152°C. The N-benzoyl derivative has m.p. 172-4° and the O,N-dibenzoyl compound, m.p. 166-8°C. Treatment with CH2N2 gives Salsolidine (q.v.). The structure, 1:2:3:4-tetrahydro6-hydroxy-7-methoxy-l-methylisoquinoline has been confirmed by synthesis.
