ABSTRACT:
The preparation of macrocyclic molecules from linear, synthetic thioester precursors is disclosed. An excised thioesterase domain isolated from either a polyketide synthases (PKS) or non-ribosomal peptide synthetases (NRPS) multido system catalyzes the cyclization reaction. Thioester substrates also are described that are efficiently cyclized by the method of the present invention. Additionally, macrocyclic molecules, including macrolactones and macrolactams, that are prepared by the macrocyclization methods of the invention are described.
