Abstract
Abstract The reaction of 3-ethoxycarbonyl-2-methyl-5-( d - arabino -tetritol-1-yl)furan with 2-methyl-2-propanethiol in acid media yielded a mixture of 5-(1- S - ert -butyl-1-thio- d - arabino - and - d - ribo -tetritol-1-yl)-3-ethoxycarbonyl-2-methylfuran ( 2 and 3 ). Longer reaction times yielded a mixture of 2 and 3 , and 3-ethoxycarbonyl-2-methyl-5-(4-thio-β- d -erythrofuranosyl)furan. 5-(4- S - tert -Butyl-4-thio- d - arabino -tetritol-1-yl)-3-ethoxycarbonyl-2-methylfuran has been synthesised and, on treatment with acid, underwent ring closure to afford mainly 8 and also the α-anomer 11 .
