| abstract |
The present invention relates to photoactivable protecting groups containing a diarylsulphid chromophore, a method for the synthesis thereof and their use as photoactivable protecting groups using maskless photolithography based array synthesis. wherein R2 is [Formula II] or wherein R2 is [Formula III] or [Formula IV] wherein R7 is a natural amino acid, a non-natural amino acid or an amino acid derivative forming an urethan bond to formula Ib, or wherein formula IV represents the carboxy function of a natural amino acid, a non-natural amino acid or an amino acid derivative, forming an ester bond to formula Ib. |
