Syntheses of Camalexin, Indolopyridocoline and Flavopereirine

Article abstract of DOI:10.1016/0040-4020(94)00987-6

A short synthetic route to the phytoalexin camalexin 7 and a convergent approach to the alkaloids indolopyridocoline 8, 6,7-dihydroflavopereirine 15 and flavopereirine 9 are presented.Starting from well accessible precursors, these total syntheses highlight the preparative potential of a new method for indole synthesis based on the formation of the C2-C3 bond by low-valent titanium induced reductive coupling of oxo-amides.
