[reaction: see text] A highly regioselective borane-reductive ring opening of the 4,6-O-benzylidene-D-hexopyranosides to the corresponding 6-alcohols in excellent yields at room temperature via various metal trifluoromethanesulfonates as catalysts is described here. Its application in the synthesis of 1,4-dideoxy-1,4-imino-L-xylitol is also highlighted.

This study presents a highly regioselective borane-reductive ring opening method for benzylidene acetals, enabling the synthesis of 1,4-dideoxy-1,4-imino-L-xylitol in excellent yields at room temperature.
