ChemInform Abstract: Polyethylene Glycol (PEG-400): An Efficient and Recyclable Reaction Medium for the Synthesis of Novel 1; 5-Benzodiazepines and Their Antimicrobial Activity.
An efficient and convenient synthesis of heteryl ( E)-styryl sulfones is described. Reaction of an 3-(2-bromoacetyl)coumarin with sodium ( E)-styrenesulfinates yields the corresponding styryl sulfones promoted by polyethylene glycol (PEG-400) as an efficient reaction medium at room temperature
An efficient, inexpensive and environmentally friendly synthesis of novel isoxazole substituted spirooxindole-pyridopyrimidine/indenopyridine/chromenopyridine/naphthyridine/quinoline derivatives has been developed.
