摘要:
A method for peptide synthesis using an N-�N'-nitroso-(R')carbamoyl!amino acid as the starting compound. The compound is separated into N.sub.2, R'OH and N-carboxyanhydride of formula (II). ##STR1## The compound (II) together with an amino acid or peptide with at least one free .alpha.-amino function is introduced into a reactive medium to obtain a dipeptide or a higher peptide than the added peptide.
摘要:
Process for preparing R.sub.F CH.sub.2 CH.sub.2 OH alcohols from R.sub.F CH.sub.2 CH.sub.2 I by reaction with a Zn/Cu metallic couple in the presence of a dissociation solvent having a water content of about 0.25 molar or less, oxidizing the resulting organometallic intermediate, and hydrolyzing the resulting product to form the corresponding perfluorinated alcohol. The perfluorinated alcohols are well known and are useful as intermediates for the production of valuable surface active agents as well as other useful materials.
