A method of preparing macrocycles using solid support chemistry and thioesterases is disclosed. Also disclosed are novel macrocycles.
which contains fragmentsD and C. After extension at the carboxyl function by esterification with the hydroxy ester 10, the seco compounds 37 and 42 were obtained. Ring closure was achieved by macrolactamization in the presence of TBTU as condensing agent. This work features a streamlined synthesis of the hydroxy ester 10, a short synthesis of the amino acid 14 by enantioselective alkylation of the
