Shibata, Makoto published the artcileTotal syntheses of patellamides, cytotoxic cyclic peptides from a marine tunicate, Recommanded Product: (R)-tert-Butyl (3-methyl-1-oxobutan-2-yl)carbamate, the publication is Tennen Yuki Kagobutsu Toronkai Koen Yoshishu (1985), 267-74, database is CAplus.
The structures of patellamides A, B, and C have been proposed to be cyclic peptides I, II, and III, resp. I and II were synthesized by solution methods, but these synthetic peptides were not identical with natural patellamides B and C. An inspection of evidences used for the originally assigned structures and a synthetic study on the partial hydrolyzate of patellamide B indicated that the structures of patellamides B and C could be reassigned as cyclic peptides IV and V, resp., having the reverse order of amino acid residues. This deduction was confirmed by the syntheses of revised structures IV and V, which were completely identical with natural patellamides B and C, resp. The structures of patellamide A was analogously revised as cyclic peptide VI by its synthesis.
