Solid-phase synthesis of phenolic steroids: Towards combinatorial libraries of estradiol derivatives

The 16β-(azidopropyl) derivative of estradiol (7) was synthesized and coupled to aminomethyl resin via a photolabile o-nitrobenzyl linker. Condensation of the corresponding iminophosphorane with activated acids successfully gave amides. Photocleavage resu
