, p. 3029 - 3036 (1996)
Diels-Alder reactions of the title 3-vinylindole 2 with N-phenylmaleimide, maleimide, DEAD and DMAD are described. From Compound 10, obtained from 2 and DMAD, Carbazomycin B (1) was prepared.

Total syntheses of carbazomycins A and B were demonstrated using a ytterbium-catalyzed Diels-Alder reaction with (silyloxyvinyl)indole as a diene. The densely substituted benzene ring of the target compound was successfully constructed by functionalization of a hydrocarbazolone intermediate and subsequent aromatization using N-bromosuccinimide.
Synthesis of carbazomycin B by radical arylation of benzene

Iodination of 2-methoxy-3,4-dimethyl-5-nitrophenol followed by acetylation yields (6-iodo-2-methoxy-3,4-dimethyl-5-nitrophenyl) acetate. Reduction with iron and acetic acid followed by reaction with methyl chloroformate then provides N-methoxycarbonyl-3-acetoxy-2-iodo-4-methoxy-5,6-dimethylaniline. Treatment of this substance in benzene at reflux with tributyltin hydride and a catalytic quantity of diphenyl diselenide leads to the formation of N-methoxycarbonyl-3-acetoxy-2-(2,5-cyclohexadienyl)-4-methoxy-5, 6-dimethylaniline which on exposure to phenylselenenyl bromide affords a phenylselenenyl tetrahydrocarbazole. Oxidation deselenation and rearomatization are achieved by heating with tert-butylhydroperoxide finally affording carbazomycin B after saponification.
Transition metal complexes in organic synthesis, part 54.1 Improved total syntheses of the antibiotic alkaloids carbazomycin A and B
Knoelker, Hans-Joachim,Froehner, Wolfgang
, p. 6915 - 6918 (2007/10/03)
Considerably improved total syntheses of the carbazole antibiotics carbazomycin A and B are reported using a convergent iron-mediated one-pot construction of the carbazole framework by oxidative cyclization in the air.
Synthesis of the Carbazole Alkaloids Carbazomycin A and B and Hyellazole
Moody, Christopher J.,Shah, Pritom
, p. 376 - 377 (2007/10/02)
The first synthesis of carbazomycins A and B (1) is described; the route involves Diels-Alder reaction of 1-methylpyranoindol-3-one with ethyl 3-trimethylsilylpropynoate followed by functional group interconversions; the marine alkaloid hyellazole
