Solid-phase synthesis of a library based on biphenyl-containing trypsin-like serine protease inhibitors

The solid-phase synthesis of a library based on an unusual biphenyl-containing trypsin-like serine protease inhibitor is described. Key to this effort was the synthesis of a highly functionalized aryl boronic acid reagent which required the development of a novel and efficient method to convert a triflate to a pinacolboronate in large scale.

A novel and efficient method for synthesizing a highly functionalized aryl boronic acid reagent in large scale was developed. A hug biphenyl scaffold library for trypsin-like serine protease inhibitor by solid-phase synthesis is described.Figure optionsDownload as PowerPoint slide
