Abstract
1,3-dimethyl-4,5-diaminouracil has been used as an efficient protecting group for the carbonyl moiety in sugars by the formation of the imine group. The protection reaction is carried out under mild conditions, the yields are quantitative in most of the cases, and the protecting group is completely recovered and reused. After per-acetylation, deprotection is accomplished at room temperature with aqueous formic acid to produce acyclic acetylated sugars in good global yield.

Aims & Scope
Letters in Organic Chemistry publishes original letters (short articles), research articles, mini-reviews and thematic issues based on mini-reviews and short articles, in all areas of organic chemistry including synthesis, bioorganic, medicinal, natural products, organometallic, supramolecular, molecular recognition and physical organic chemistry. The emphasis is to publish quality papers rapidly by taking full advantage of latest technology for both submission and review of the manuscripts.
The journal is an essential reading for all organic chemists belonging to both academia and industry.
