The synthesis of compounds with the general structure 27 is as follows. The boc-protected thiazolidine carboxylic acid 1 is converted to amino-ketones 26 with requisite grignard reagents 25 in the presence of oxalyl chloride. Final compounds 27 are obtained by a DCC-mediated coupling of 26 and 4 followed by deprotection of the P2 phenol. Final compounds were purified either by flash chromatography or preparative HPLC.
