The invention is directed to compounds of formula (I) wherein A, B, D, E, X and Y are defined in the description. These compounds are useful precursors for the synthesis of monomers for Peptide Nucleic Acids (PNA).
Multicomponent synthesis of novel amino acid–nucleobase chimeras: a versatile approach to PNA-monomers
paper describes a multicomponent approach to novel totally protected precursors of PNA-monomers viaUgi 4CC. The obtained bisamides are converted into several partially protected PNA-monomers or derivatives thereof using three different procedures. Methods for hydrolysis are shown to be dependent on the nature of the isocyano component required for Ugi 4CC. Several novel monomers suitable for oligomer
