The present invention relates to novel phosphoramidites, A-n-bz, C-n-bz, C-n-ac, G-n-ac and U are produced with an HPLC purity of greater than 98% and
31
P NMR purity greater than 99%. A novel process of reverse 5′→3′ directed synthesis of RNA oligomers has been developed and disclosed. Using that method demonstrated high quality RNA synthesis with coupling efficiency approaching 99%.
