Synthesis of (t-2-benzyloxymethyl-t-3-hydroxy-r-1-methoxycarbonyl)-tetrahydrofuran from an arabino-lactone triflate with K<sub>2</sub>CO<sub>3</sub>–MeOH
The arabino-lactone triflate 4 reacts with K2CO3 in MeOH to give the oxetane ester 5 and the tetrahydrofuran ester 6 in a ratio dependent upon the reaction temperature.
Ring contraction of 2-o-trifluoromethanesulphonates of α-hydroxy-γ-lactones to oxetane carboxylic esters
Flourine and azide substituents are introduced into an oxetane ring by nucleophilic displacement reactions; the syntheses and anti-viral activities of 9-(2'-azido-2'-deoxy-beta-D-erythro-oxetanosyl)-adenine and of 9-(2'-deoxy-2'-fluoro-beta-D-erythro-oxetanosyl)-adenine are reported.
