资源简介：
The trisubstituted cyclohexenone 12, generated through
a palladium-catalyzed Ullmann cross-coupling reaction between o-iodonitrobenzene and a 4,5-trans-disubstituted
2-iodo-2-cyclohexen-1-one, engaged in a tandem reductive cyclization
process upon exposure to hydrogen gas in the presence of Raney cobalt.
As a result, the 1,5-methanoazocino[4,3-b]indole 13 was obtained and this could be readily elaborated to the
racemic modifications of the alkaloids uleine, dasycarpidone, noruleine,
and nordasycarpidone (1–4, respectively).
