Description

CAS: 765-69-5 | C6H8O2 | 112.128 g/mol

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.

Aplicaciones
El 2-metilciclopenta-1,3-diona es un sintón eficiente para la síntesis de (±)-α-cuparenona. La alquilación de 2-metilciclopenta-1,3-diona (A) con bromuro 2-(1-naftil) de etilo produce solo el producto de o-alquilación. Se obtienen mezclas de derivados C y O-alquilo. La adición de Michael de 2-metilciclopenta-1,3-diona a metilvinilcetona en agua produce 2-metil-2-(3-oxo-butil)-1,3-ciclopentanodiona (3), un importante intermediario de la química natural del producto. La 2-metillciclopenta-1, 3-diona es un sintón eficiente para la síntesis de (±)-α-cuparenona.

Solubilidad
Solubilidad en metanol caliente (casi transparente).

Notas
Almacenar en un lugar fresco. Mantenga el recipiente bien cerrado en un lugar seco y bien ventilado. Almacenar lejos de los agentes oxidantes fuertes.
