ChemInform Abstract: A Simple Approach to the One-Pot Three Component Synthesis of 4H-Pyrimido [2,1-b] Benzothiazole Derivatives Using Polyethylene Glycol (PEG-400).
An efficient, inexpensive and environmentally friendly synthesis of novel isoxazole substituted spirooxindole-pyridopyrimidine/indenopyridine/chromenopyridine/naphthyridine/quinoline derivatives has been developed.
[PEG-TEA]LP, as a new biodegradable ionic liquid catalyst, was successfully synthesized, characterized, and applied to the one-pot pseudo-five-component synthesis of bis(pyrazolyl)methanes.
