Asymmetric Transfer Hydrogenation of Arylidene-Substituted Chromanones and Tetralones Catalyzed by Noyori-Ikariya Ru(II) Complexes: One-Pot Reduction of C═C and C═O bonds

3-Arylidenechroman-4-ones and 2-arylidene-1-tetralones are hydrogenated to cis-benzylic alcohols in dr's and er's up to 99:1 via a C═C and C═O one-pot reduction in the presence of 2-5 mol % Noyori-Ikariya-type RuII chiral complexes and HCO2Na as a hydroge

An improved synthesis of homoisoflavanones

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.

Phase Transfer Catalysed Hydroxymethylation of 2'-Hydroxydihydrochalcones: A New Synthesis of Homoisoflavanones

2'-Hydroxydihydrochalcones having different oxygenation patterns in rings A and B, on treatment with formalin in chloroform-saturated aqueous potassium carbonate biphase system in the presence of a phase transfer catalyst (tetra-n-butylammonium hydrogen s
