A photolabile linker based on a thiohydroxamic acid has been shown to be an efficient ‘traceless’ linker, revealing an aliphatic CH bond on photolysis at 350 nm. Methods for the synthesis, loading and photolytic cleavage of the linker are described.

We describe the use of a sulfide linkage as a safety-catch linker. This linker is significantly stable to acidic as well as basic conditions and allows transformations to be carried out on solid supports. Moreover, its cleavage is facile by applying Pummererrearrangement after transforming it to sulfoxide.
