Synthesis of 3-Substituted Pentane-2,4-diones: Valuable Intermediates for Liquid Crystals
Cativiela, Carlos,Serrano, Jose L.,Zurbano, Maria M.
, p. 3074 - 3083 (2007/10/02)
General procedures for the synthesis of six series of 3-substituted pentane-2,4-diones are described.The diones were used as intermediates in the preparation of pyrazoles, isoxazoles, and coordination complexes whose mesogenic properties have been studied.Nematic and smectic phases have been obtained in a number of cases, and relationship between molecular structure and mesogenic properties has been explored.

Kuebel, Boerries
, p. 1392 - 1401 (2007/10/02)
Condensation of 4-hydroxybenzaldehyde (1) with ethyl acetoacetate (2a) or acetylacetone (2b) gives 3a and 3b, respectively, which on hydrogenation afford the 2-(4-hydroxybenzyl)-1,3-dicarbonyl compounds 4a and 4b, respectively.These react with hydrazines
