To overcome the problem of depurination in oligoDNA synthesis, we tried to fine-tune the acid lability of the DMTr group by adding a substituted styryl group on the phenyl ring. The styryl groups could buffer the electron donating nature of the methoxy group and enabled the fine-tuning of the acid lability.
