Jaspal, Sharda,Grover
, p. 1782 - 1783 (2007/10/03)
2′-Hydroxydihydrochalcones i.e. 1-(2-hydroxyphenyl)-3- phenylpropanones having different oxygenation patterns in ring-A and ring-B, on refluxing with paraformaldehyde powder and aqueous diethylamine in ethanol give the corresponding homoisoflavanones in excellent yields.

The absolute configuration of the homoisoflavonoidal components, 4-O-methylsappanol, 4-O-methylepisappanol, sappanone B, 3-deoxysappanone B and 3'-deoxysappanone B, from Caesalpinia sappan L. were determined on the basis of chemical transformations and the optical properties.Keywords - Caesalpinia sappan; Leguminosae; Sappan Lignum; heartwood; homoisoflavonoid; absolute configuration
A New Biogenetic Approach for the Synthesis of Homoisoflavanones
Makrandi, J. K.,Grover, S. K.
, p. 739 - 743 (2007/10/02)
2'-Hydroxydihydrochalkones on refluxing with methylene iodide in acetone medium in the presence of anhydrous potassium carbonate have been found to yield bi(dihydrochalkonyloxy)methanes and homoisoflavanones.
