5-Methoxyindole Usage And Synthesis

Chemical Properties

white to light brownish crystalline powder

Uses

5-Methoxyindole (cas# 1006-94-6) is a compound useful in organic synthesis. It can be used to synthesis 1-(Phenylsulfonyl)-5-methoxy-1H-indole.

Preparation

The synthesis of 5-methoxyindole from 5-methoxy-2-oxindole: Conversion of 5-methoxy-2-oxindole to 5-methoxyindole was accomplishedby the chlorination of 5-methoxy-2-oxindole with triphenylphosphine-carbontetrachloride in acetonitrile followed by the catalytic reduction of a chlorine atom in 66% total yield.

Definition

ChEBI: 5-methoxyindole is a member of indoles.

Reactions

5-methoxyindole was treated with sodium hydroxide and phenylsulfonyl chloride in the presence of a catalytic amount of tetrabutylammonium bromide to afford 1-(phenylsulfonyl)indole and 5-methoxy-1-(phenylsufonyl)indole in excellent yields of 100%.
