4-tetrahydropyrazino[1,2-a]indoles were synthesized from 2-cyanoindole. (R)-4-Methyl-1,2,3,4-tetrahydropyrazino[1,2-a]indole was obtained by the Mitsunobu reaction. Stereoselective reduction of 4-substituted 1,2,3,4-tetrahydropyrazino[1,2-a]indoles gave 4-substituted 1,2,3,4,10,10a-hexahydropyrazino[1,2-a]indoles. (4R, 10aR)-4-Methyl-1,2,3,4,10,10a-hexahydropyrazino[1,2-a]indole was synthesized.
摘要 以2-氰基吲哚为原料合成了4-取代的1,2,3,4-四氢吡嗪并[1,2-a]吲哚。(R)-4-Methyl-1,2,3,4-四氢吡嗪并[1,2-a]吲哚通过Mitsunobu反应获得。4-取代的1,2,3,4-四氢吡嗪并[1,2-a]吲哚的立体选择性还原得到4-取代的1,2,3,4,10,10a-六氢吡嗪并[1,2-a]吲哚。(4R, 10aR)-4-Methyl-1,2,3,4,10,10a-六氢吡嗪并[1,2-a]吲哚合成。
