摘要：

A convenient general procedure for the synthesis of cyclic peptides is reported. The linear intermediates, obtained via solid-phase synthesis, are cyclized by the coupling agent diphenylphosphoryl azide (DPPA). A simple procedure allows rapid isolation of the cyclic products. Peptides of varying ring size have been prepared in amounts of up to 50 g. A significant variation of cyclization yield with sequence has been observed in the conversion of three different linear peptides to the same cyclic product. Several related linear sequences have also been cyclized, and the results are discussed. © 1979, American Chemical Society. All rights reserved.
