Synthesis of a dihydropyrano[3,2-e]indole as a rotationally restricted phenolic analog of the neurotransmitter serotonin
摘要:
1-(2-Dimethylaminoethyl)-8,9-dihydropyrano[3,2-e]indole (1) has been synthesized via a six step procedure involving a Claisen rearrangement of a 5-allyloxyindole-3-glyoxamide. This novel heterocycle (1) represents a rotationally restricted phenolic analog of the neurotransmitter serotonin [3-(2-aminoethyl)-5-hydroxyindole].
