Methylene acetals as protecting group - An improved preparation method

A facile method to protect vic diols, 1,3 diols and other hydroxyl functions as methylene acetals is achieved by treating the relative substrates with POCl3 or SOCl2 in DMSO. The good yields obtained, the good solubility of many orga

Synthesis of Methyl-O-4,6-methylene-α-D-mannopyranoside by Transacetalisation Reaction from Dimethoxymethane

Lithium bromide assisted transacetalisation of methyl-α-D-mannopyranoside (3) with dimethoxymethane led to the title compound (4) in moderate yield.Compound 4 is a new and stable monoacetal which is formed to the exclusion of the expected corresponding diacetal (5) or the rearranged diacetal (6).
