First general synthesis of monosilyl acetals. Trimethylsilyl trapping of the intermediate in DIBALH reduction of carboxylic acid esters using trimethylsilyl trifluoromethanesulfonate☆

Add time:08/12/2019    Source:sciencedirect.com

The intermediate generated by the DIBALH reduction of carboxylic acid esters reacts with trimethylsilyl trifluoromethanesulfonate (TMSOTf) in the presence of pyridine to afford the corresponding monosilyl acetals in good yields.
