## Abstract Cyclic peptides containing sarcosine, cyclo‐(Pro‐Sar‐Gly)~2~, cyclo‐(Sar‐Sar‐Gly)~2~, cyclo‐(Sar~4~), and cyclo‐(Sar~6~) have been synthesized by the cyclization of the __p__‐nitrophenyl ester of linear peptides. The __tert__‐butoxycarbonyl group was used as the __N__^α^‐protecting grou

✦ Synopsis
Cyclixation of a diary1 ether containing an or, m-amino acid residue leads to cyclic peptides which resemble the vancomycin binding pocket The glycopeptide antibiotics, exemplified by vancomycin, are believed to act by complexation with the car-boxy1 terminal of a pentapeptide unit which usually forms cross links in the bacterial cell wall'. This complexation has been shown in virro initially by the W experiments of Perkins2 and, more recently, by the

## Abstract 1. The extent of racemization and the coupling yield in peptide synthesis were studied under high dilution conditions. The azide method yielded the best results. 2. Five linear penta‐peptide precursors related to gramicidin S were subjected to cyclization in order to study how the diffe
