The first asymmetric total syntheses of urgineanins A, B, and D - potent antiproliferative homoisoflavonoids - were achieved by utilizing Pd-catalyzed allylic substitution of the allylic acetate with arylboronic acids for introduction of the C rings of homoisoflavonoid skeleton. Several unnatural urgineanin analogues were also prepared in this manner.
