An equimolar soln. of glycine isopropyl ester hydrochloride and D-alanine methyl ester in methanoll 3 M tris(hydroxymethyl)aminomethane containing a little 2-mer-captoethanol adjusted to pH 9.5 with 10 MNaOH, 0.5 eqs. of N-benzyloxycarbonyl-phenylalanine methyl ester and a little (crude) papain added successively, the mixture shaken for 1 min, methyl isobutyl ketone added, and stirred vigorously at room temp, for 12 h - Z-Phe-Gly-D-Ala-OMe. Y 57%. A 2-fold increase in yield was observed with methanol as cosolvent compared with dioxane. The method appears to be quite...

Di-l-propynyl ketone (MI-90) and primary amines (ethylamine, isopropyl-amine) or amino acids that are unsubstituted in the a-position (glycine, ll-alanine, e-aminocaproic acid, glycylglycine, glycylleucine, alanylglycine) give enamines (W-91), which form V-substituted lutidones when their sodium salts are heated in water or their esters are heated in xylene. When 2-substituents are present, cyclization oocurs when their calcium salts or amides are heated in aqueous alkali. When heated in the presence of Triton B and DMF, a-alanyl-amide and di-I-propynyl ketone give the lutidone. ... 

Early development of the Passerini reaction focused on the convergent synthesis of complex depsipeptide derivatives. In 1962 Ugi described the use of isopropyl a-isocyano ester 40 as a glycine precursor to prepare the simple... 

Ugi reaction of 73 with isopropyl isocyanide,. /V-Boc-2-(indan-2-yl)glycine and leucine methyl ester was applied to the synthesis of compound 296 - oxytocin antagonist with pKi 10.0 [1].
