1,2,3,4-Tetrahydroisoquinoline → (S)-2-(oxiran-2-ylmethyl)-1,2,3,4-tetrahydroisoquinoline

Participants

Reaction Steps

To a solution of 1,2,3,4-tetrahydroisoquinoline (5 g, 7.52 mmol) in THF (100 mL) was added KF (8.57 g, 150.4 mmol) at 0° C. (R)-oxiran-2-ylmethyl 3-nitrobenzenesulfonate (10.7 g, 41.4 mmol) was added to the reaction in 1 h. The solution was stirred at room temperature overnight. The solid was removed by filtration and washed with THF. The solution was then concentrated and the residue used for next step without further purification (11.3 g Yield 80%). LCMS (m/z): 190.1 (M+1).
