Postsynthetic modification of DNA via threoninol on a solid support by means of allylic protection
摘要:
We have developed a facile but versatile method to introduce functional molecules into DNA on a CPG support. Threoninol, whose amino group was protected with an (allyloxy)carbonyl (Alloc) group, was introduced into DNA via the corresponding phosphoramidite monomer. After selective deprotection of the Alloc group by treatment with palladium(0), a dye with a carboxyl group could be introduced into the DNA on the CPG Support through an amide bond.
