Microwave-Assisted Synthesis of Novel Tetra-O-acetyl-β-D-glucopyranosyl Thiosemicarbazones of Substituted Isatins

Some new substituted isatin (2,3,4,6-tetra-O-acetyl-β-D-glucopyranosyl)thiosemicarbazones were synthesized by reaction between 2,3,4,6-tetra-O-acetyl-bgr;-D-glucopyranosyl thiosemicarbazide and corresponding substituted isatins using conventional and microwave-assisted heating method. It is shown that the latter gave higher yields of products.
