Pentaethylbenzoic acid was produced in good yield bv saponification of the amide with 100% phosphoric acid, while under the same conditions pentamethylbenzamide was completely decarboxylated to pentamethylbenzene. The cyclisation of o-(pentaethylbenzoy1)-benzoic acid yielded an alkaline soluble, ye

Abstract
The synthesis of L‐valyl‐δ‐CBO‐L‐ornithyl‐L‐leucyl‐D‐phényl‐alanyl‐L‐proline, which could be an intermediary product for the synthesis of Gramicidin S, has been achieved.

## Abstract The synthesis of a nonapeptide exhibiting bradykinin‐like properties is described. Condensation of CBO‐(nitro)Arg‐Pro‐OH with H‐Pro‐Gly‐NHNH‐CTO and selective splitting of the CTO‐group yielded CBO‐(nitro)Arg‐Pro‐Pro‐Gly‐NHNH~2~. CBO‐Phe‐ Ser‐N~2~ was condensed with H‐Pro‐Phe‐(nitro)Arg

N‐CBO‐L‐arginyl‐L‐arginine is condensed with L‐prolyl‐L‐valine methyl ester and, after splitting of the CBO group, L‐arginyl‐L‐arginyl‐L‐prolyl‐L‐valine methyl ester is obtained. This is condensed with N‐trityl‐glycyl‐N^ϵ^‐CBO‐L‐lysyl‐N^ϵ^‐CBO‐L‐lysine and, after selective splitting of the trityl gr
