Green and diastereoselective synthesis of trans-3-(5-methylisoxazol-3-yl)-3,4-dihydro-2H-naphtho[2,3-e][1,3]oxazines
Reaction between aromatic aldehydes and 3–methyl-1-phenyl-2-pyrazoline-5-one catalyzed by nano-SiO2/HClO4 in water under reflux provided a simple and efficient route for the synthesis of 4-((5-hydroxy-3-methyl-1-phenyl-1H-pyrazol-4-yl)(aryl)methyl)-3-methyl-1-phenyl-1H-pyrazol-5-ol derivatives in high yields.
متن کاملStructural and biological investigation of ferrocene-substituted 3-methylidene-1,3-dihydro-2H-indol-2-ones.
The Knoevenagel condensation of 1,3-dihydro-2H-indol-2-one with ferrocene carboxaldehyde afforded an approximate 2:1 mixture of the geometrical isomers (E)- and (Z)-3-ferrocenylmethylidene-1,3-dihydro-2H-indol-2-one respectively in an overall 67% yield; the air and solution-stable isomers were readily separated by preparative thin layer chromatography and their structures were unequivocally elu...

متن کاملSOME UNUSUAL REACTIONS OF 3-PHENYLAMINOISOXAZOL-5 (2H)- ONES
3-Phenylaminoisoxazol-5(2H)-ones,s ubstituted on nitrogen with an isoquinoline or quinazoline group, react with tertiary amine bases to give imidazo annelated compounds. When the N-substituent is a nitropyridine, 2-aminoindole derivatives are formed instead. Evidence is presented that the reactions proceed by initial addition of the tertiary arnine to C-4
