Abstract

In Fortsetzung der Arbeiten von H. Zahn und N. H. La France^1)^ wurde aus dem Insulin als weiteres Peptid L‐Threonyl‐L‐prolyl‐L‐lysyl‐L‐alanin, das in der B‐Kette die B~27–30~‐Sequenz bildet, dargestellt. Die Synthese gelang mit Hilfe der Carbodiimidmethode^2)^ durch gliedweisen Aufbau vom Carboxylende her.
