Abstract
Dibenzyloxydihydrobenzoxathiin 1, which resisted debenzylation with SiCl4/LiI, was effectively debenzylated with SiCl4/LiI in the presence of a catalytic amount of BF3. The HCl salt of the bis-debenzylated product 2 was isolated in 90% yield and 99% purity. This enhanced dealkylation activity has also been observed with other substrates.
