An efficient synthetic route to homocarbonyltopsentine
Montagne, Cyril,Fournet, Guy,Joseph, Beno?t
, p. 1533 - 1535 (2003)
Efficient synthesis of homocarbonyltopsentine Ia, starting from readily available triiodoimidazole 9 and 3-formylindoles 2 and 18 is described. The key steps of the synthesis are selective halogen-metal exchanges at the imidazole nucleus and subsequent ad
