L-Acetyl-6-nitroindole

The values of the 1-hydroxy moiety of (5)-(- -)-iVb-acetyl- 1-hydroxytrypto-phan methyl ester (32), methyl l-hydroxyindole-3-butylate (33), iVb-methoxy-carbonyl-l-hydroxytryptamine (34), 1-hydroxymelatonm (19), l-hydroxy-6-nitroindole (35), and l-hydroxy-5-nitroindole (36) are determined to be 9.8, 8.4, 8.2, 8.1, 6.9, and 6.8, respectively (Fig. 2) (2000H1881). Thus, 1-hydroxyindoles are weak acids, stronger than phenol and weaker than succinimide. Therefore,... [Pg.108]

Dehydrogenation of indoUnes using DDQ has been used to prepare 6-nitroindole (benzene, reflux, 86%) [32], 7-bromo-5-nitroindole (98%) [33], 6-azido-4,5,7-trif-luoroindole (benzene, 88%) [34], 4,5,6,7-tetrahydroindole (benzene, reflux, 68%) [35], methyl l-acetyl-2-cyclopro-pyl-5-methoxyindole-3-carboxylate (toluene, reflux, 87%) [36], 5,6-dicyano-l-methylindole (benzene, reflux, 97%)... [Pg.544]
