Synthesis of 2,2'-biindolyls; Potential intermediates for indolocarbazole alkaloids

Jesudoss,Srinivasan

, p. 1701 - 1708 (1994)

The synthesis of 2,2'-biindolyls oxygenated in the benzenoid ring is reported. Wittig-Horner reaction of the phosphonate esters of 1- benzenesulfonyl-2-bromomethyl-3-substituted indoles with o- nitrobenzaldehydes followed by deoxygenation with triethyl phosphite gave 2,2'-biindolyls.
