METHOD OF OBTAINING URETHANE-PROTECTED N-CARBOXYANHYDRIDES OF ALPHA AMINO ACIDS.

摘要

The invention relates to a method of preparing urethane-protected N-carboxyanhydrides of alpha amino acids. The inventive method enables the synthesis of urethane-protected N-carboxyanhydrides of alpha amino acids in the presence of a catalytic quantity of triethylene diamine without the addition of a tertiary amine-type base.
