Synthetic Strategy

A synthetic strategy towards tricholomic acid and acivicin has been established using the aldol condensation of N-pyruvilideneglycinatoaquocopper(II) and an optically active aldehyde derived from S-malic acid as the key bond-forming reaction. Although a viable strategy was developed, no asymmetric induction was observed.
