ABSTRACT:
Methods for synthesizing oligomers containing hydroxy acids, and optionally containing other types of monomers or oligomers such as amino acids, carbohydrates, nucleotides and peptides, are provided which are rapid, simple, and readily automated. The oligomers have a C-terminal and an O, S or N-terminal end. The starting hydroxy acid can be covalently bound at either the C-terminal or O, S or N-terminal end to a solid support. The bond to the solid support can be an amide, thioester, ester, phosphate, silyl ether, carbamate, benzyl ether, or other linkage that can be cleaved either chemically or enzymatically.
