A combination of BF3 · Et2O and DTBMP was established to be an efficient promoter of β-glucosylation of both phenols and carboxylic acids with a peracetylated glycosyl fluoride (2). This new method achieved remarkably high yields and β-selectivity.
A new approach for the synthesis of cinnamoyl glycoside has been developed via iodination-Heck reaction sequence startingfrom phenyl glycoside. Successful application of this procedure accomplished the construction of the right core structure of amino-sugar antibiotic, glycocinnasperimicin D.
