, p. 927 - 930 (2011/11/12)
A three component one-pot protocol was investigated for the synthesis of methylene bis isoxazolo[4,5-b]-pyridine-N-oxides from commercially available materials.
Chemistry of Heterocylces: Part VIII - Synthesis of Isoxazolylethylpyrazoles
Reddi, K. Malla,Rao, C. Janakirama,Murthy, A. Krishna
, p. 212 - 213 (2007/10/02)
The base-catalysed addition of acetylacetone to 3-methyl-4-nitro-5-styrylisoxazoles (II) leads to the Michael adducts 3-pentane-2,4-diones (III).These β-diketones (III) undergo cyclization with hydrazine sulphate and phenylhydrazine to furnish pyrazoles (IV) and N-phenylpyrazoles (V), respectively.
Ethylene-diheterocycles: Part I - Synthesis of 5--3-methyl-4-nitroisoxazoles
Rao, C. Janakirama,Reddy, K. Malla,Murthy, A. Krishna
, p. 997 - 998 (2007/10/02)
Michael addition of acetylacetone to 3-methyl-4-nitro-5-styrylisoxazoles (I) in triethylamine leads to 3--2,4-pentanediones (II).The pentanediones (II) undergo cyclisation with hydroxylamine to give 5-ω
