Abstract

Synthetic studies on the novel fungicidal oligopeptides, echinocandins (1b and 1c), are described. The constituent amino acids 5–8 were synthesized in a stereocontrolled manner from the chiral starting materials, 5a, 6a and 7a, respectively. The coupling of these amino acids was characterized by the use of unprotected amino acid as the C-terminal and 2- pyridyl thiol ester as the N-terminal, and the coupling was performed in the presence of 1-( ...
