资源简介：
A three-step
synthesis of masked 2,3-diaminoindole 1 from 2-iodo-3-nitro-1-(phenylsulfonyl)indole
(2) has been developed. Treatment of 1 with
trifluoroacetic acid generates the unstable 2,3-diamino-1-(phenylsulfonyl)indole
(3), which can be trapped with α-dicarbonyl compounds
to afford 5H-pyrazino[2,3-b]indoles 7–10.
