H. Huang et al., SYNTHESIS OF A NEW SERIES OF CYCLIC PSEUDOPEPTIDES CONTAINING PYRIDINE AS BACKBONE MODIFIER, Synthetic communications, 28(24), 1998, pp. 4639-4647
A new class of cyclic pseudo-peptides which contains pyridine and cyst
ine in the backbone structure was synthesized by a simple three-step p
reparation. The structures of products were characterized by spectrosc
opic and conventional analytical methods.
