tert-Butyl 2,4-dideoxy-3,5-O-(1-methylethylidene)-D-erythro-hexonate

It often serves as a chiral building block or intermediate in carbohydrate chemistry and organic synthesis. Its protecting groups allow selective reactions on unprotected positions for the synthesis of complex molecules. tert-Butyl 2,4-dideoxy-3,5-O-(1-methylethylidene)-D-erythro-hexonate is a protected sugar derivative in which the hydroxyl groups at positions 3 and 5 are masked as an isopropylidene acetal, and the carboxyl group is tert-butyl esterified.
