Enantioselective Synthesis of the (1S,5R)-Enantiomer of Litseaverticillols A and B
MORITA, Akira | Kiyota, Hiromasa | KUWAHARA, Shigefumi
An enantioselective synthesis of the (1S,5R)-enantiomer of litseaverticillols A and B was accomplished in line with our previously reported synthetic pathway for their (1R,5S)-enantiomer. The use of “EtSCeCl₂” prepared from EtSLi and CeCl₃, instead of previously employed EtSLi itself, for the formation of thiol ester intermediates prevented any undesirable epimerization occurring in the process.
