, p. 507 - 512 (2016)
4,5-Bis(butoxy)-2-nitrobenzaldehyde and 4,5-bis(tert-butoxycarbonyloxy)-2-nitrobenzaldehyde, as well as their fluorine-18 labeled derivatives (the half-life of F18 is T1/2 = 110 min) were synthesized for use as precursors in the synt
SYNTHESIS OF 5,6-DIHYDROXYINDOLE: A NOVEL REDUCTIVE CYCLIZATION OF (E)-4,5-DIHYDROXY-2,β-DINITROSTYRENE
Murphy, Bryan P.,Banks, Harold D.
, p. 321 - 330 (2007/10/02)
A unique catalytic reductive cyclization of (E)-4,5-dihydroxy-2,β-dinitrostyrene (1) to 5,6-dihydroxyindole (2) is reported.Compound 1 is obtained either by one-step CF3CO2H deprotection of 4,5-dibenzyloxy-2,β-dinitristyrene (7), or by an improved two-step demethylenation of 6-nitropiperonal (5), followed by condensation with CH3NO2.

Avery, Mitchell A.,Verlander, Michael S.,Goodman, Murray
, p. 2750 - 2753 (2007/10/02)
A number of possible approaches to the ring-aminated isoproterenol derivative 4-ethyl>-5-amino-1,2-benzenediol have been attempted.Of these, the total synthesis using the commercially available starting material 6-nitrop
