Oikawa, Hideaki,Matsuda, Isamu,Ichihara, Akitami,Kohmoto, Keisuke

, p. 1223 - 1226 (2007/10/02)

Degradation of AAL-toxin 1 a host-specific phytotoxin and synthesis of model aminotriol 7a-7d allowed us to determine the absolute configuration of C(1)-C(5) fragment as 2S, 4S and 5R. Unusually rigid conformation of this acyclic fragment was also discussed.
