Abstract

Abstract : Novel silylated diols and polyols were prepared using a recently developed synthesis route with bifunctionalized silyl triflates. These silyl derivatives include two triflate functions, which allow a selective protection of two hydroxy groups. Moreover, the conformation of the silyl chain in the silane backbone led to exceptional UV properties. Abstract : Oligosilyl triflates were used to protect cyclitols. Depending on the conformation of the OH groups a regioselective protection of the cyclitols was possible. Additionally, several oligosilyl derivatives show a remarkable behavior in the UV due to their σ‐conformation.
