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].

The efficient total synthesis of (-)-serotobenine (1) has been achieved by constructing an optically active dihydrobenzofuran ring via a rhodiumcarbenoidmediated intramolecular C-H insertion reaction, which was developed by our group. Then the possibility of racemization of 1 was investigated using optically active synthetic 1.

The synthesis of two rotationally restricted phenolic analogs (1a and 1b) of the neurotransmitter serotonin have been accomplished. The syntheses of 8.9-dihydropyrano[3,2-e]indole (13a) and 7,8-dihydropyrano[2,3-f]indole (13b), which formed the template for these targets, are outlined. These novel fused-indoles represent rotationally restricted phenolic analogs of 5-hydroxyindole. The reaction sequence
