[reaction: see text] Two series of seco-pseudonucleoside synthons were synthesized from (R)-(+)-alpha-hydroxy-gamma-butyrolactone and (R)-(-)-pantolactone by aminolysis, side-chain protection, dimethoxytritylation, and phosphitylation or solid-phase attachment. The phosphoramidites and solid supports were used in automated DNA synthesis to prepare oligonucleotides modified with one or more 2,4-dihydroxybutyramide
