Efficient and low cost synthesis of the 2-(tert-butyldiphenylsilyloxymethyl)benzoyl chloride for the protection of nucleobases

The title compound was easily obtained starting from cheap phthalide in four steps with an overall yield of 67%.

A new protected acyl protecting group for exocyclic amino functions of nucleobases

2-(Tert-butyldiphenylsilyloxymethyl)benzoyl chloride (SiOMB-Cl) reacts with the per-O-trimethylsilylated d-nucleosides C,G and A to give, after removal of the Si(Me)3 groups and 5′-O-protection with 4,4′-dimethoxytrityl chloride (DMT-Cl), the corresponding N-SiOMB-5′-O-DMT derivates, the SiOMB groups of which can easily be removed by fluoride ion. The SiOMB protected nucleosides proved to be suitable building units for the preparation of DNA fragments in solution and on a solid support.
