As the paragraph descriping shows that 18881-17-9 is playing an increasingly important role.

18881-17-9, (S)-(1,2,3,4-Tetrahydroisoquinolin-3-yl)methanol is a isoquinoline compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated

18881-17-9, The experimental procedure used for this reaction was adapted from the literature.15 To a solution of (S)-3-hydroxymethyl-1,2,3,4-tetrahydroisoquinoline 4 (1.42 g, 8.70 mmol) in dioxane (20 mL) and water (10 mL) at 0 C, was added dropwise a solution of potassium hydrogen carbonate (4.30 g, 41.0 mmol) in water (10 mL) over 15 min followed by addition of CbzCl (1.63 g,9.50 mmol). The mixture was stirred for 1.5 h at 0 C and then atambient temperature for a further 1.5 hours. Completion of the reaction was monitored by TLC in hexane:ethyl acetate (60:40,Rf = 0.32). The solvent was removed under reduced pressure to afford the crude compound (S)-benzyl 3-(hydroxymethyl)-1,2,3,4-tetrahydroisoquinoline-2-carboxylate 5, which was purified by column chromatography using 0-40% ethyl acetate in hexane as the eluent to yield pure compound 5 as an oil. Yield1.85 g (74%). [alpha]D20 (c = 0.35, in CH2Cl2). IR numax/cm-1 = 3418, 3030,2945, 1676, 1415, 1345, 1219, 1119, 1027 and 741.
