설명
2-Methylcyclopentane-1,3-dione is an efficient synthon for the synthesis of (±)-α-cuparenone. The alkylation of 2-methylcyclopentane-1,3-dione (A) with 2-(1-naphthyl)ethyl bromide gives only the O-alkylation product. Mixtures of C- and O-alkyl derivatives are obtained. Michael addition of 2-methylcyclopentane-1,3-dione to methyl vinyl ketone in water gives 2-methyl-2-(3-oxo- butyl)-1,3-cyclopentanedione (3), an important intermediate of natural product chemistry. 2-Methylcyclopentane-1, 3-dione is an efficient synthon for the synthesis of (±)-α-cuparenone.
This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.
