As part of an effort to generalize the synthesis of substituted tetrahydrofurans from protected β-hydroxy aldehydes, a series of common alcoholprotectinggroups was screened for compatibility with the methodology. Employing a β-(triisopropylsilyloxy)aldehyde resulted in a low yield of tetrahydrofuran, while the other protectinggroups all afforded good yields of tetrahydrofurans.
