Metabolite Identification
Common Name2-Methylundecanal
Description2-Methylundecanal, also known as aldehyde mna or fema 2749, belongs to the class of organic compounds known as medium-chain aldehydes. These are an aldehyde with a chain length containing between 6 and 12 carbon atoms. This process involves starting with simple achiral aldehydes and converting them to their SAMP hydrazones then obtaining the corresponding chiral hydrazones using RAMP as a chiral auxiliary. It is used as a fragrance component in soaps, detergents, and perfumes. 2-Methylundecanal is an extremely weak basic (essentially neutral) compound (based on its pKa). This compound smells herbaceous, orange, and ambergris-like. CH3(CH2)7CH2CH2 + H2 + CO → CH3(CH2)10CHOCH3(CH2)10CHO + HCHO → CH3(CH2)8C(CH2)CHO + H2OCH3(CH2)8C(CH2)CHO + H2 → CH3(CH2)8CH(CH3)CHO2-Methylundecanal contains one asymmetric carbon atom. The glycidate then undergoes saponification followed by decarboxylation. The resulting solution is over 50% 2-methyleneundecanal.
