✦ Synopsis


3'-a-Carboxymethyl-2"O-methyl ribonucleosides, which are important building blocks for the construction of high affinity amide modified antisense oligonucleotides, have been synthesized from the corresponding 2'-O-methyl ribonucleosides via catalytic hydrogenation of their 3'-deoxy 3'-methoxycarbonyl-methylidene derivatives. Reduction of the olefinic double bond proceeds in good to excellent yields and with ct/fl-product ratios > 9/1.
