New compounds which have potent V.sub.2 -vasopressin antagonistic activity are prepared by a 1,6-cyclization using peptide bond formation. The structures of the compounds are characterized by a Pas.sup.1,6 or Tas.sup.1,6 cyclized unit. Also a chiral synthesis of the optically pure Pas intermediates is described.
通过肽键形成的1,6-环化制备了具有强效V.sub.2-加压素拮抗活性的新化合物。这些化合物的结构由Pas.sup.1,6或Tas.sup.1,6环化单元表征。同时,描述了对光学纯Pas中间体的手性合成。
