Synthesis of Various Spiro-Pyranooxoindoles Using Vitamin B12 as an Efficient Biocatalyst
The present study aims to discuss the synthesis of various spiropyrano-
oxoindole derivatives through a reaction involving isatin, malononitrile, and a CH-acid
source in the presence of vitamin B12.
Eco-friendly solvents were utilized to synthesize the spiro-pyranooxoindole,
resulting in high yields of all synthesized heterocyclic systems. Isatin and malononitrile
were reacted with β-dicarbonyls as CH-acids in the presence of vitamin B12.
The results indicate that vitamin B12 is highly effective in generating spiro-pyranooxoindole
derivatives. All synthesized compounds closely match previously reported compounds.
In conclusion, a new and effective method for synthesizing spiro-pyrano-oxoindole
has been demonstrated using vitamin B12 as a biocatalyst.
