Systematic strategy for the synthesis of cyanobacterin and its stereoisomers. 2. Asymmetric total synthesis of the 2- and 3-epimers of dechloro-cyanobacterin.
Stereocontrolled total syntheses of the (2S,3R)- and (2R,3S)-isomers of the non-chlorinated analog of cyanobacterin, a potent photosynthesis inhibitor, were achieved. Since both the (2R,3R)- and (2S,3S)-isomers of this compound had been previously synthesized from the same starting material, a systematic strategy for the synthesis of all stereoisomers could be established.
