LA TRANSFORMATION D'INDOLINES EN INDOLES ET D'AUTRES REACTIONS APPARENTEES

Barton, Derek H.R.,Lusinchi, Xavier,Milliet, Pierre

, p. 4949 - 4952 (1982)

Phenylseleninic anhydride reacts rapidly with indolines at 0 deg C to give, when the β-position is substituted, the corresponding indoles.When the β-position is unsubstituted β-phenylselenoindoles are formed.These are readily reduced by nickel boride to the parent indole.Tetrahydroisoquinoline is dehydrogenated with comparable ease.Phenylseleninic acid is also an efficient agent for these dehydrogenations.
