DOCUMENT TYPE: Journal CA Section: 34 (Amino Acids, Peptides, and Proteins) The total synthesis of ulithiacyclamide (I) was achieved by the two-fold ring closure of bifunctional pentafluorophenyl ester II followed by cyclizing the threonine residues of the resulting cyclic peptide III with SOCl2. II was prepd. from fragments IV, V, and [Me3CO2CNHCH(CO2H)CH2S]2. .
