An improved synthesis of the key intermediates (3 and 8) for the synthesis of beta-hydroxywybutines [[R-(R*,S*)]- and [S-(R*,R*)]-4], the most probable structures for the minor base from ratliver tRNA(Phe), has been achieved by the Wittig reaction between 1-benzyl-7-formylwye (1) and the phosphorane derived from (R)-2-[(methoxycarbonyl)amino]-3-(triphenylphosphonio)propanoate (10), followed by methylation
