Calcium bis-L-pyroglutamate and lithium L-pyroglutamate are prepared by reaction of the metal hydroxides with L-pyroglutamic acid in aqueous solution. In the solid state calcium bis-L-pyroglutamate adopts a layer structure, built up by sixteenmembered rings consisting of four L-pyroglutamate ligands
The dehydro-residue containing peptides N-Ac-dehydro-Phe-L-Leu-OCH3 ( I ) and N-Acdehydro-Phe-NorVal-OCH, (11) were synthesized by the usual workup procedures. The peptides crystallize from their solutions in methanol in space group P6,: ( I ) a = b = 12.528(2) A, c = 21.653(5) A; (11) a = b = 12.53
There are numerous possible gamma-amino acids with different degrees of substitution and with various constitutions and configurations. Of these the gamma4- and the like- and unlike-gamma(2,4)-amino acids have been previously used as building blocks in gamma-peptides. The synthesis of gamma2-, gamma
