One step conversion method of indole-3-carboxaldehydes into indole-3-acetonitriles is developed. Applying the method, 4-nitro- (7 a), 4-phenyl-(7 b), 4-iodo- (7 c), 4-methoxy- (7 d), and 4-benzyloxyindole-3-acetonitrile (7 e) are available in two steps from indole-3-carboxaldehyde (4).

A facile synthesis of 6-hydroxyindole-3-acetic acid 1a, which is the proposed aromatic subunit of NPTX-1~6, is described. Radical cyclization of isonitrile 2 successfully afforded 9 in high yield. The aromatic subunit of NPTX-1~6 was confirmed as 4-hydroxyindole-3-acetic acid 12 by comparison of the 1H-NMR spectra with those of authentic 4- and 6-hydroxyindole-3-acetic acids.
