Rationelle Synthese von α‐ L ‐Homoprolin und einiger Derivate. Herstellung von 7‐α‐ L ‐Homoprolin‐bradykinin

Optically pure α‐ L ‐homoproline can be prepared with good yield from N‐bnezyloxycarbonyl‐ L ‐proline through its diazoketone‐derivative. Preparation of derivatives of α‐ L ‐homoproline used in peptide chemistry, and of 7‐α‐ L ‐homoproline‐bradykinin, as well as biological investigation of the latter are described.
