A new, general method for the highly regioselective introduction of substituents into the 3-position of 5-unsubstituted 4-O-alkyl tetronates has been developed. 3-Lithiated 4-alkoxy-2-triisopropylsilyloxyfurans generated from the corresponding 3-iodoprecursors via halogen-metal exchange serve as key intermediates.

Highly regioselective 3-hydroxyalkylations of boron 4-methoxy-2-furanolates: A new entry to 5-unsubstituted and 5-monosubstituted 3-acyl-4-o-methyl tetronates

Boron 4-methoxy-2-furanolates generated in situ from 5-unsubstituted and 5-monosubstituted 4-O-methyl tetronates undergo highly regioselective 3-hydroxyalkylations with aldehydes to give 5-unsubstituted and 5-monosubstituted 3-acyl-4-O-methyl tetronates, respectively, in good overall yields after oxidation of the intermediate alcohols with 2-iodoxybenzoic acid.
