  • 7-Methoxy-2,2-dimethyl-3,4-dihydro-2H-1-benzopyran-4-one

    CAS:
    <p>7-Methoxy-2,2-dimethyl-3,4-dihydro-2H-1-benzopyran-4-one is a labile, hydrolysed and deprotonated chlorochromene derivative. It is the synthetic precursor to indole derivatives. This compound is used as a reagent in the ring opening of piperidine with acetaldehyde to form 1,4,5,6-tetrahydropyridines. 7MDC is also used for the synthesis of substituted indoles from anion condensation with pyridine. The yields are low because this compound has a high reactivity towards nucleophiles and cannot be stored for long periods of time.</p>
