1,2,3,4-TETRAHYDROISOQUINOLINE Chemical Properties,Usage,Production

Synthesis

To a solution of the isoquinolinone (1.156 g, 9.90 mmol) and tert-butyl alcohol (0.88 mL, 11.9 mmol) in THF (30 mL) at −78 °C was added liquid ammonia (about 280 mL). Lithium was added in small pieces until the blue coloration persisted, after which the solution was stirred at −78 °C for 30 min. The blue coloration was dissipated with piperlyne, 4-methoxybenzyl chloride (4.83 g, 31.00 mmol) in THF (5 mL) was introduced by syringe, and the mixture was stirred for an additional 150 min at −78 °C. Solid ammonium chloride was added and then the ammonia was allowed to evaporate. The pale yellow residue was partitioned between CH2Cl2 (30 mL) and water (40 mL). The layers were separated, and the aqueous layer was extracted with CH2Cl2 (2 × 30 mL). The combined organic layers were washed with 10% sodium thiosulfate solution (20 mL), dried over magnesium sulfate, and concentrated. Flash chromatography (EtOAc:hexane, 2:1) on silica gave 2.21 g (75%) of the tetrahydroisoquinolinone.

Description

1, 2, 3, 4-TETRAHYDROISOQUINOLINE belongs to tetrahydroisoquinoline compound, which is encountered in a number of drugs, tubocurarine, one of the quaternary ammonium muscle relaxants^1-3. It is used as a reagent in the preparation of4-(1, 2, 4-oxadiazol-5-yl) piperidine-1-carboxamides as antiproliferative tubulin inhibitors¹. It can be used for the synthesis of 1, 2, 3, 4-tetrahydroisoquinoline-3-carboxylic acid (Tic), which has strong applications in peptides and peptidomimetics design and discovery². 1, 2, 3, 4-tetrahydroisoquinoline has been made into some derivatives with potential for prevention of parkinsonism⁴, cancer treatment5 and acting as Anticonvulsant Agents⁶.
