Description

3,4-Di-O-acetyl-L-arabinal is a synthetic compound that belongs to the class of monofluorides. It has been synthesized from l-arabinose by a stereoselective process, with triflic acid as the catalyst and propargylation as the key step. The synthetic pathway starts from an acid hydrolysis of L-arabinose to yield 3,4-di-O-acetyl-L-arabinonic acid. This acid is then converted to 3,4 diacetyl L arabinonic acid with acetic anhydride and acetic acid in the presence of triethylamine. The final product is then obtained by reacting this intermediate with 1 equivalent of sodium fluoride in tetrahydrofuran (THF) using catalytic reduction with sodium borohydride at 0 °C. The major advantage of this synthetic process is that it provides two stereoisomers: (
