Lithium tetrafluoroborate is found to be an efficient catalyst for the chemoselective protection of both aromatic and aliphatic aldehydes as 1,3-oxathiolanes and 1,3-dithianes under mild reaction conditions. Due to the neutral reaction conditions, this method is compatible with acid sensitive substrates.
