  A Modular Synthetic Approach toward Exhaustively Stereodiversified Ligand Libraries

  摘要：

  This report describes a modular approach to the synthesis of stereodiversified natural product like libraries. Monomers 2 and 3 were coupled in parallel by silyl tethered olefin metathesis to generate all 16 stereoisomers of cis-enediols 1. All 16 stereoisomers were incorporated into chimerae having flanking peptidic segments. These chimerae exhibited a broad range of hydrophobicities, raising the possibility that stereochemical variation might be used to tune the pharmacologic properties of small molecules.
