Abstract

Application of the silicon linkage strategy to the solid-phase synthesis of the rich-electron o- anisidine derivatives is described. The protective t-Boc group was easily removed with B- catechol borane and the isocyanate was successfully prepared with the mild reagent (t-Boc) 2O DMAP. Carbamates, ureas or amides were prepared and released by cleavage with TFA at room temperature. This method can be used to prepare small focused libraries with ...
