and novelsynthesis of bis(tert-butyl)- 1-pyrenylmethyl-silyl group (TBMPS) has been reported having fluorescent properties conferred by the pyrenyl group. This silyl group being base labile is efficiently used for one-pot protection of the 5-OH of the nucleosides. While incorporated terminally at the 5-OH of long sequences viz. AA TGG AGC CAG T and GC TAT GTCAGT TCC CCT TGG TTC TC, this group is also
