Multifunctional liquid phase carriers (LPCs) and methods of using LPCs for
the preparation of biopolymers are provided. The LPCs are highly
symmetrical compounds that possess more than two points of attachment for
biopolymer synthesis. The LPCs have the formula Sp(X.sup.1).sub.n, where
Sp is a highly symmetrical moiety such that all X.sup.1 groups are
equivalent. X.sup.1 is a functional group that is suitable for biopolymer
synthesis, including OH, SH, NH.sub.2, COOH and the like. Biopolymers
that may be produced using the methods provided include oligonucleotides,
peptides, protein nucleic acids (PNAs) and oligosaccharides. Analogs of
the biopolymers may also be prepared using the methods.
