We report herein some recent progress in the reaction of 2-TMSOF (2-trimethylsilyloxyfuran) with achiral aldehydes in the presence of a new catalytic system (which does not use the expensive Binol catalyst) yielding the corresponding butenolides with good diastereomeric ratios (d.e. = 90 %) and moderate e.e.’s (50 %).
