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.
新的化合物,具有强效的V.sub.2-vasopressin拮抗活性,通过肽键形成的1,6-环化制备。这些化合物的结构特征是通过Pas.sup.1,6或Tas.sup.1,6环化单元来表征的。此外,还描述了光学纯Pas中间体的手性合成。
