Organocatalytic transformation of 1,3-diketones into optically active cyclohexanones
Gryko, Dorota
, p. 1377 - 1383 (2005)
The domino Michael-aldol reaction of 1,3-diketones with MVK in the presence of L-proline furnished highly substituted cyclohexanones in a regio- and stereocontrolled manner. When the reaction was performed in NMP, high yields (up to 93%) and enantioselectivities up to 80% were observed.
Synthesis and anti-microbial activities of 1,3,5-trisubstituted-pyrazole derivatives containing a pyridyl moiety

Claisen condensation of ethyl isonicotinate with different acetophenones gave the corresponding pyridyl-β-diketones, while the treatment with hydrazine hydrate yielded 3,5-disubstituted-1H-pyrazoles, which then converted 1,3,5-trisubstituted-pyrazole deri
1,3-Diketones from acid chlorides and ketones: A rapid and general one-pot synthesis of pyrazoles
Heller, Stephen T.,Natarajan, Swaminathan R.
, p. 2675 - 2678 (2007/10/03)
1,3-Diketones were synthesized directly from ketones and acid chlorides and were then converted in situ into pyrazoles by the addition of hydrazine. This method is extremely fast, general, and chemoselective, allowing for the synthesis of previously inaccessible pyrazoles and synthetically demanding pyrazole-containing fused rings.
