Abstract
A short access to 2-carbethoxy-3-(5-imidazolyl)indoles (13, 14, 16), f eaturing Pd-catalyzed cross coupling between 3-iodoindoles (10-12) and imidazolostannane (9) has been developed. These derivatives when subj ected to tandem modified Curtius rearrangement-intramolecular electroc yclization led to the pyridones (19-23) which are key intermediates in the synthesis of the analogs (31), (33) and (36) of the naturally occ urring cytotoxic alpha-carbolines grossularines-1 and -2 (1,2).
