By addressing the relativestereochemistry of the four acyclic portions via organic synthesis, the complete relativestereochemistry of maitotoxin (MTX) has been established as 1B. The relativestereochemistry of the C.1−C.15 portion was elucidated via a two-phase approach: (1) the synthesis of the eight diastereomers possible for model C, representing the C.1−C.11 portion, and the eight diastereomers
modern organic synthesis, chemoselectivity is recognized as an important factor in the development of new methodologies. Chemoselective nucleophilic addition to amide carbonyl centers is a challenge because classical methods require harsh reaction conditions to overcome the poor electrophilicity of the amide carbonyl group. We have successfully developed a reductive nucleophilic addition of mild nucleophiles
