A mild and highly efficient one-pot asymmetric transfer hydrogenation (ATH) of challenging, electron-rich 3-arylidenechroman-4-ones is reported.
Hippophae rhamnoides L. is an edible fruit for both medicine and food. Twelve new phenylpropanoid-homoisoflavonoid derivatives were isolated from this plant. Compounds (3–5, 7–9) exhibited hepatoprotective and hypolipidemic activities, respectively.
This review examines the progress in the total syntheses of these unique complex structures, highlighting their challenges and opportunities.
The review is on synthesis of different classes of isoflavonoids that include isoflavones, isoflavanones, isoflavans, isoflavenes, pterocarpans, rotenoids, coumaronochromones, and coumestans.
Facile syntheses of a series of novel fused-ring flavanone systems via Mannich reactions and o-QM cycloadditions and evaluation of their anticancer effects.
