Here we report a novel and efficient method for the regioselective mono-deprotection of di-tert-butylsilylene acetals derived from 1,3-diols consisting of primary and secondary alcohols. The ammonium fluoride-mediated reactions of pyripyropene A derivative, thymidine and uridine derivatives, methyl β-d-glucofuranoside, and pyranoside derivatives each gave the corresponding primary alcohol with high regioselectivity.
