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