Gm. Makara et Gr. Marshall, A FACILE SYNTHESIS OF 3-SUBSTITUTED PIPECOLIC ACIDS, CHIMERIC AMINO-ACIDS, Tetrahedron letters, 38(29), 1997, pp. 5069-5072
Three protected 3-substituted pipecolic acid analogs were prepared as
constrained chimeric amino acid building blocks. The concise synthetic
route enables the synthesis of other derivatives with sidechain funct
ionality of amino acids as well. (C) 1997 Elsevier Science Ltd.
