Photochemical release of various functional groups

Bochet, Christian G.

In: Pure and Applied Chemistry, 2006, vol. 78, no. 2, p. 241-247

The photochemical liberation of functional groups is an attractive alternative to the traditional chemical approach. Several photolabile protecting groups have been developed in the past decades, but they were mainly designed to protect amines and carboxylic acids. In this account, we present some of our recent work on the photochemical release of other functions, such as silanols, aldehydes,...

Chromatic Orthogonality in Organic Synthesis

Bochet, Christian G.

In: Synlett, 2004, no. 13, p. 2268-2274

A major challenge in organic synthesis is the selective reaction of a functional group in the presence of others. This can be achieved by using an appropriate reagent, tuned to react exclusively at the desired center. An alternate approach would be to use a single reagent, and to transmit from the outside the information as to where it should react. This account describes the use of light as a...
