|Title:|| N-substituted amino acids as intermediates in the preparation of acyl derivatives of 1,2,3,4-tetrahydroisoquinoline-3-carboxylic acids|
|Abstract:||N-substituted amino acids are described which when coupled with 1,2,3,4-tetrahydroisoquinolines result in substituted acyl derivatives of 1,2,3,4-tetrahydroisoquinoline-3-carboxylic acids as anti-hypertensive agents. The novel intermediates are in turn prepared by reacting an amino acid such as alanine with 2-bromo-4-phenyl butanoic acid or an ester thereof.|
