摘要:
AbstractSchmidt reaction of the pyrazolo‐β‐(p‐anisyl)‐propionic acid3gave the pyrazolo‐anisylethylamine4. The related alkaloids5and6were obtained via double Mannich reaction of4with the bis‐Mannich base of cyclopentanone and transamination with gramine respectively. The pyrazolo‐phenylalanine9was obtained from the EAA adduct7, through its Schmidt reaction to give8followed by hydrolysis, whereas the pyrazolo‐amino acid12resulted from the hydrolysis of the corres
