Efficient synthesis of nicotianamine and non-natural analogues
Bouazaoui, M'Barek,Larrouy, Manuel,Martinez, Jean,Cavelier, Florine
, p. 6609 - 6617 (2010)
An efficient synthesis of nicotianamine has been achieved by using a new strategy based on N-alkylation. Sulfonamide activation proved to be necessary for the alkylation of the primary amine and the 2-(trimethylsilyl)ethanesulfonyl group was easily introd
