A new family of unnatural amino acids possessing a tetrahydroindole moiety is obtained by nucleophilic addition of various amino acids to the triple bond of 2-benzoylethynyl-4,5,6,7-tetrahydroindoles. The reaction proceeds chemo-, regio- and stereospecifically in the presence of sodium hydroxide to give the Z-isomeric products in 35–72% yields.
