Oleandrose

Oleandrose is a type of carbohydrate with the chemical formula C7H14O4. With a six-carbon chain, it is classified as a hexose. With two hydroxyl groups replaced with hydrogen atoms, it is a dideoxy sugar. The hydroxyl group at C3 is methylated.

Occurrence

Oleandrdose is found in the leaves of Nerium oleander and may contribute to the toxicity of the plant.[1][2] Oleandrose is also a component of several naturally-occurring chemical compounds including the avermectins (emamectin, abamectins, ivermectin, and others), the macrolide antibiotic oleandomycin, and the cardiac glycoside oleandrin.

Laboratory syntheses of L-oleandrose[3] and DL-oleandrose[4] have been reported.
