However, the ketone VI/63 did not undergo transamidation reaction either under acidic or under basic conditions5 When the primary amino function in VI/63 was protected (as a phthalide by Nefkens reagent [49] [50]), the planned transformation of VI/64 to VI/1 via VI/66, VI/68, VI/69, outlined above and in Scheme VI/14, was realized in an overall yield of 56 % [10]. The behavior of the ketone VI/63 suggest an aminoacetal formation of type VI/73 [51]. Such a compound can be of interest for metallion transport phenomena in plants, because isomers of VI/63 are natural products and may have some functions in nature. A detailed analysis of this abnormal behavior is in progress [51].
