Nitroindoline → 2,3-dihydro-1H-indol-1-amine

Participants

Reaction Steps

Substituted indolines are prepared such as by the procedures described in Scheme 10. Substituted amino-indolines 37 are prepared from the nitroindoline 35 and a ketone in the presence of NaHB(OAc)3 to form the 1-substituted indoline 36. The nitroindoline 36 is hydrogenated, such as with H2 in the presence of a catalyst, such as Pd/C, to yield the amino-indoline 37.
