摘要:
2-Substituted allyl alcohols 9 and 14 were prepared starting from butane-1,2,4-triol and glycerol, respectively. Mitsunobu condensations of 9 and 14 with purine and pyrimidine bases, followed by deprotection, afforded a number of acyclonucleosides having 4-hydroxy-2-methylenebutyl or 3,3-bis(hydroxymethyl)-2-methylenepropyl chain.
