Conclusions

  1. 1.

    2-Acetyl-1,3-cyclopentanedione reacts with diazomethane at the carbonyl group in the ring to give the 1(3)-O-methylderivative.

  2. 2.

    2-Acetyl-1,3-cyclohexanediones react with diazomethane predominantly at the acetyl keto group.

  3. 3.

    The 1(3)-O-methyl ether of 5-phenyl-2-acetyl-1,3-cyclohexanedione reacts with diazomethane at the trigonal C(3) centers.
